Although the PEX pipes are flexible and require fewer fittings, but making a decision which fittings are suitable for your plumbing system is very tough.
You know the fittings have a wide range of variation. It’s often confusing which one should I buy for my next plumbing project and which product is most reliable.
Also, PEX connection does not require glue or solvent like PVC or other plastic pipe connection. They become connected by the mechanical union. So, perfect measurement is must for union.
There are numerous manufacturers and third parties, some of them are popular but the newer company also delivered good fittings.
Best PEX Fittings & Connections
Before going into details, here is our top recommendation for your plumbing system.
PEX Fittings & Connections Reviews
In this section, I will guide everything about PEX fittings; types, materials, connection methods, and compatibility.
The connection method varies from fittings to fittings and they are arranged into 5 categories
1. Crimp Fittings
Crimp fittings are the most popular and standard variation in the PEX plumbing system.
They are available in most of the online store and home improvement supply houses.
Typically they are available in two forms:
- Brass (ASTM F1807 standard)
- Poly alloy (ASTM F2159 standard)
Both of them are compatible with any PEX tubing (type A, B, C) and brands.
Method of Connection
- Crimp method: To connect a PEX pipe with a fitting, this method requires a crimp tool and copper crimp rings.
- Cinch (Clamp) Method: It requires a cinch tool and stainless clamps.
2. Push-to-Connect Fittings
Push fitting is a special connector which locks two pipes together. They don’t require any tools, glue or other mechanic means to connect.
They can connect any PEX-A,B,C pipes, CPVC or copper pipes but can’t be used with PEX-AL-PEX, PolyButylene or PVC pipes.
Also, their disconnection is easy, just require a disconnect clip to remove the pipe from fittings.
Best PEX Push-to-Connect Fittings

Many times we require end capping off pipes or fittings. The SharkBite end cap is great for that purpose.

If you make connection mistakenly or you need to disconnect a push fitting, SharkBite disconnect clip is for you.

Just place the clip with the non-branded face against the release collar. Then push it against the collar and pull the pipe by twisting.
The SharkBite disconnect tongs are same as disconnect clip.
