What are push fittings made of?
Push-fit plumbing fittings are also known as push fittings or push-on fittings. They’re specially made for use on PEX, CPVC, and rigid copper water pipes. Some fittings are smaller and specially made for use in plastic tubing used with ice makers, aquariums, and water filters.
What are faucet O-rings made of?
O-rings are mechanical gaskets with a round cross section. They are used to prevent gas and fluid leaks in static and dynamic applications and are manufactured from various types of elastomers. Some of the common types of O-ring materials include PTFE, Nitrile (Buna), Neoprene, EPDM Rubber and Fluorocarbon (Viton).
What creates the water tight seal in a push fit fitting?
The fittings are engineered with a ring of metal spurs inside the fittings that tightly grip the pipes when they are inserted into the fitting sockets. Regardless of the brand, push-fit fittings all have a similar internal structure that allows them to create a watertight seal when they are pushed onto a pipe.
Do you need plastic inserts for push fit?
The simple answer is yes, always use an insert when installing Speedfit pipes as it supports the shape of the pipe. We have two types of insert – the ‘STS’, or Superseal for plastic to plastic, and the ‘TSM’ for plastic to compression.
What does the O in O-ring stand for?
Other seals Although the O-ring was originally so named because of its circular cross section, there are now variations in cross-section design.
Can you reuse push fit connectors?
Certain push-fit fittings, such as Speedfit brand, can be removed by hand and reused. Others may need a special tool to remove them for reuse. Some brands cannot be reused at all.
Why are O rings important in plumbing fittings?
You are probably aware that O-rings play an important role in push fit fittings in the plumbing industry. It’s the part of the pipe connection that is used to make a seal, preventing any risk of leakage from the water inside. It has low insertion forces and allows the pipework and fitting to rotate.
What’s the proper way to install an O ring?
The diagram below which can be downloaded in PDF shows good tips on how to properly install an O-ring. The first O-ring installation procedure is to lightly coat the O-ring seal with lubricant that is compatible with your system. Secondly, if necessary, cover any sharp edges upon installation to avoid cutting or damaging of the O-ring seal.
What do you need to know about the O-ring?
The O-ring – or toric joint as it is also known – is present in most fluid power systems today, and one of the most integral components for any piping system. It’s highly likely you’ve used large numbers of O-rings throughout your career to date, but how much do you know about them?
Who are the manufacturers of push fit fittings?
Push-fit technology has grown in popularity over the years, with a number of manufacturers joining in the game. We only offer quality fittings from SharkBite, ProBite, and the original push-fit innovators, John Guest.

What are the names of push fit plumbing fittings?
Sharkbite and Gatorbite are two well-known brand names. Regardless of the brand, push-fit fittings all have a similar internal structure that allows them to create a watertight seal when they are pushed onto a pipe.
What causes a leak in an O ring?
Sharp edged pipes can cut or displace the O-ring during installation, and leaks can also be caused by inserting a poorly scored pipe into the fitting. Scoring damage can act as a miniature trench underneath the O-ring, creating recesses where water ingress occurs.
