Overview of push-to-connect plumbing fittings

Push-to-connect plumbing fittings utilize an internal sealing mechanism that creates a secure connection to the pipe when it is inserted into the fitting. No clamps, glues, or tools are required to join the pipe to the fitting. Just push the pipe in, and the connection is made.

Most push-to-connect fittings are made of plastic with an internal O-ring seal. When the pipe is inserted, the O-ring compresses to create a tight friction fit. The fittings also contain stainless steel teeth or claws that grip the pipe for added security.

Push-to-connect fittings are available for both copper and plastic piping in a wide range of styles, including elbows, tees, adapters, couplings, and end caps. They provide a fast, simple way to make watertight connections for plumbing repairs, remodels, and new installations.

Introducing Aqualock and SharkBite – two popular brands

Both Aqualock and SharkBite have become go-to brands for push-to-connect fittings. They are designed to provide leak-proof, durable, and easy push-fit connections.

Aqualock is manufactured by HB Group, and was introduced to the market in 2015. The fittings are made from engineered composite plastic with a stainless steel grip ring.

SharkBite is produced by RWC, originally launched in Australia in 2004 under the name Cash Acme. SharkBite fittings consist of an advanced thermoplastic with stainless steel teeth and a nitrile rubber O-ring.

While the two brands share similarities, there are some notable differences that consumers should be aware of when deciding between Aqualock and SharkBite.

Thesis statement: Aqualock and SharkBite are both high-quality options, with some key differences in performance, price, and reputation.

Aqualock Fittings

Aqualock is a relative newcomer to the push-to-connect fitting industry, but has quickly made a name for itself for innovative design and reliable performance.

Company history and product overview

The Aqualock brand was launched in 2015 by HB Group, a fitting manufacturer based in Wisconsin. HB Group had already produced push-to-connect fittings for other brands and brought their expertise to create the Aqualock line.

Aqualock fittings are designed to provide durable, water-tight connections that can handle high pressures. They are approved for behind-the-wall installation and can be used for both potable water and radiant heating systems.

The fittings are available in a wide range of configurations for 1/2″ to 1″ copper, CPVC, PEX, and PERT pipes. The fittings allow for straight, 90-degree and T-connections. There are also coupling extenders and adapters for transitioning between pipe materials.

Materials and manufacturing process

Aqualock fittings are constructed from an engineered composite plastic body. This high-tech plastic provides both strength and flexibility.

The fittings feature stainless steel grip rings with tiny teeth that grab the pipe for a secure hold. An EPDM rubber o-ring provides the watertight seal.

The advanced materials and internal components allow Aqualock fittings to withstand pressures up to 200 PSI and temperatures up to 180°F.

The fittings are manufactured at HB Group’s facility using precision molds and automated processes. All products go through rigorous testing to ensure consistent quality.

Range of fittings and pipe compatibility

One of the advantages of Aqualock is the wide range of fitting configurations available. The lineup includes:

  • Straight connectors
  • 90-degree elbows
  • T-shaped fittings
  • Reducing couplers
  • End caps
  • Adapters
  • Extenders

This extensive selection makes it easy to find the right Aqualock fitting for virtually any copper, CPVC, PEX or PERT pipe connection need in 1/2″ to 1″ sizes.

Ease of installation

Aqualock markets their product as “The Easiest Push Fit Fitting on the Planet.” The fittings are designed for quick, straightforward installation without requiring any special tools or skills.

To install an Aqualock fitting:

  1. Cut the pipe cleanly and squarely.
  2. Deburr the pipe end with sandpaper or a knife.
  3. Mark the insertion depth on the pipe.
  4. Push the pipe into the fitting until it reaches the depth mark.

The pipe will slide over the o-ring seal and grip ring to create a secure watertight connection without leaking or popping out. No clamping, gluing or soldering is needed.

The fittings can be rotated 360° after installation to properly align the connection. To remove a fitting, simply push in the release collar while pulling out the pipe.

Price and cost considerations

Aqualock fittings have an MSRP similar to other premium push-to-connect brands like SharkBite. However, Aqualock products can typically be purchased for 20% to 30% less than comparable SharkBite fittings.

When purchased from plumbing suppliers in bulk quantities, Aqualock fittings usually range in price from $2 – $8 per fitting depending on the size and configuration. Couplings and adapters are at the lower end, while T-fittings and elbows cost more.

While Aqualock fittings carry a higher upfront cost than crimp or compression fittings, they can save significant time and labor during installation. The ability to quickly join pipes without tools or glue can result in an overall lower installed cost in many cases.

SharkBite Fittings

SharkBite is the most prominent brand name in push-to-connect fittings, known for high-quality products and innovative designs.

Company background

The SharkBite brand was launched in Australia in 2004 by Reliance Worldwide Corporation (RWC). The original patent for the technology was filed in 1975 in Australia by Cash Acme. RWC acquired Cash Acme in 2001 and trademarked the SharkBite name.

SharkBite pioneered many of the advancements in push-to-connect fitting design. RWC continues to invest heavily in R&D and holds numerous patents related to push-to-connect technology.

SharkBite launched into the US market in 2009 and quickly became the top selling push-to-connect brand in North America. They have the widest product distribution among plumbing wholesalers and home improvement retailers.

Materials used and manufacturing process

SharkBite fittings consist of an engineered thermoplastic body, stainless steel teeth, and an advanced silicone rubber seal.

The thermoplastic used in SharkBite fittings is PPSU (polyphenylsulfone). This heat and chemical resistant plastic can handle pressures up to 200 PSI.

The stainless steel teeth provide a strong grip on the inserted pipe. The teeth flex open to accept the pipe then snap back tightly.

An exclusive silicone o-ring compresses against the pipe to create a leak-proof seal. The flexible o-ring can accept out-of-round pipe and accommodates temperature fluctuations.

SharkBite maintains strict quality control standards for all products manufactured at their facilities in the US, UK, China and Australia.

Product range and pipe compatibility

The SharkBite lineup includes an extensive range of fittings in sizes from 1/4″ to 2″ for use with copper, CPVC, PEX, HDPE, and multi-layer composite pipes.

Some of the products offered include:

  • Straight couplings
  • Elbows – both 90° and 45°
  • Tees – equal and reducing
  • Adapters for joining different pipe materials
  • End stops
  • Ball valves
  • Manifold and splitter tees
  • Flexible supply lines

SharkBite fittings are certified for potable water, radient heating, gas, compressed air, and fire sprinkler systems. They can handle both hot and cold water in residential or commercial applications.

Installation and use

Like other push-to-connect fittings, SharkBite connections can be made in seconds without clamps, glue, or soldering torches. Just insert the pipe into the fitting until it hits the pipe stop.

The teeth will automatically clamp down securely on the pipe exterior. At the same time, the o-ring compresses to create a permanent seal.

SharkBite fittings will work with pipe that is slightly out of round or cut on a slight angle. However, the company recommends using a saw or PVC cutter for clean, straight cuts and sanding any burrs for optimal performance.

A SharkBite release tool or the fittings’ built-in release collar allows fittings to be disconnected by depressing the teeth mechanism. Overall, SharkBite presents a very user-friendly installation experience.

Pricing and costs

SharkBite fittings have a higher price point than value-branded push-to-connect options. But they are competitively priced with other premium fitting brands.

Retail prices for SharkBite range from around $3-$15 per fitting depending on the type, size and quantity purchased. Elbows and tees tend to cost more than couplings. Buying in bulk can save up to 20% or more.

While SharkBite fittings do come at a higher upfront price versus crimp or threaded fittings, the labor savings often balances out the material cost. In many cases, SharkBite offers a less expensive total installed cost. Their wide availability and strong reputation also provide peace of mind to many installers.

This covers the key background and product details on both the Aqualock and SharkBite brands of push-to-connect fittings. Next we will compare the two options head-to-head.
