After we say Cross-Linked Polyethylene, you would possibly surprise what it’s. But when we are saying PEX, you would possibly keep in mind these colourful pipes which might be slowly dominating the residential plumbing. Whether or not it’s copper or PEX, we have now correct fittings and becoming a member of strategies in order that we will route the pipes to all corners of the home. Talking of becoming a member of PEX Pipes, we have now PEX Crimp Connections and PEX Clamp Connections. These two connections assist us in securing the PEX Pipe to a becoming or one other pipe. However how do PEX Crimp vs Clamp connections examine? Is one sort of connection superior to different?

If you’re new to PEX Pipes and their fittings and connections, this information is only for you. Right here, we are going to discuss PEX Crimp vs Clamp Connections and show you how to perceive the variations between the 2.

What’s PEX?

PEX is brief for Cross-linked Polyethylene. It’s a sort of versatile plastic that’s bolstered with chemical compounds (cross-linking) to present it further energy. It’s fairly fashionable in Europe because the late Nineteen Sixties however took a very long time to enter the U.S. market.

The first cause for that is the security issues of the PEX pipe as folks within the U.S. typically made comparisons between PEX and PB (Polybutylene). PB Pipes had a infamous response to chlorine which broken the pipe after a brief run.

However the chemistry of PEX pipes is solely completely different. PEX Pipe producers should comply with a number of requirements, specs, and codes with very tight management of the uncooked supplies and excessive QC requirements.

Because the Nineties, contractors, plumbers, and householders within the U.S. began utilizing PEX Pipes for all kinds of plumbing necessities as they have been less expensive than copper pipes and their versatile nature means you should use them for lengthy distances in addition to bend round corners.

In the event you have a look at catalogs of PEX Pipes, then you’ll discover colourful pipes (Crimson, Blue, and White). Is there any significance to the colours of the PEX Pipes? The straightforward reply isn’t any. Colours don’t indicate any bodily or chemical properties of the PEX Pipes.

However most plumbers usually use Crimson PEX Pipes to hold scorching water and Blue or White PEX Pipes to hold chilly or municipal water.

Preserving the colour of the PEX Pipe apart, we have now three kinds of PEX Pipes: PEX A, B, and C. Of those, the PEX-A Pipes are the most costly of the three. It is because they’re of considerably greater high quality than the opposite two and much more versatile.

If you’re searching for a bang for the buck PEX set up, then the PEX-B is the only option. Typically, we don’t see PEX-C Pipes in residential plumbing.

Becoming a member of PEX Pipes

We are able to use PEX Pipes with different kinds of pipes resembling Copper and PVC. For easy residential PEX Plumbing, you may get quite a lot of fittings and instruments to hitch the pipes.

Talking of becoming a member of PEX Pipes, there are alternative ways in which you’ll be part of them. All of the fittings are mechanical and don’t require glue or cement.

Do not forget that completely different PEX Pipe producers have their respective fittings and instruments. Interchanging PEX Pipes and fittings between completely different producers is usually not attainable and never advisable both (resulting from guarantee points)

Of the several types of PEX Fittings, solely two are highly regarded. They’re Chilly Growth Fittings and Plastic or Steel Insert Fittings.

Chilly Growth Fittings

Once more, in Chilly Growth Fittings, we have now Chilly Growth Fittings with PEX Strengthened Rings and Chilly Growth Rings with Steel Compression Sleeves.

Within the first sort, we have now to first insert a PEX-Strengthened ring on the finish of the PEX Pipe. Then, earlier than inserting the PEX Pipe into the steel or plastic becoming, we have now to develop the tip of the PEX Pipe (together with the ring) utilizing a particular expander device.

After inserting the PEX Pipe into the becoming, the reminiscence of the PEX pipe will retract and kinds a good seal.

Within the second sort, we have now to insert the PEX Pipe by way of a compression sleeve, which is often made up of brass. Then develop the tip of the PEX Pipe (solely the pipe) and slide it over the becoming (steel or plastic).

The reminiscence of the pipe will retract the pipe over the becoming. Then pull the compression sleeve over the connection to compress the pipe and type a good seal over the becoming.

Plastic or Steel Insert Fittings

On this sort, we use Crimp Rings, Metal Clamps, or Metal Sleeves to compress the pipe across the becoming. The fabric of the becoming may be brass, copper, bronze, or plastic.

As that is the primary matter of this dialogue and the PEX Crimp vs Clamp comparability, we are going to see extra about these within the subsequent part.

What’s PEX Crimp Connection?

The PEX Crimp is a single piece of copper ring that seals the connection between the PEX Pipe and the becoming (steel or plastic). The dimensions of the PEX Crimp Ring is marginally bigger than the PEX Pipe to be able to slide the pipe by way of it.

To make a PEX Crimp Connection, first, insert the PEX Pipe by way of the Crimp Ring. Push it barely above after which insert the tip of the PEX Pipe into the becoming.

Now, slide the Crimp Ring over the connection, and utilizing a particular PEX Crimp Instrument, press the crimp ring till it kinds a superb seal.

You need to use the PEX Crimp Ring with each metals in addition to plastic PEX fittings. Even should you don’t have the PEX Crimpling Instrument, you should use a easy plier to press down the crimp ring over the connection.

After crimping the ring, use a go/no-go gauge to test whether or not the connection is nice or not.

  • Though PEX Crimping Instruments can be found, you may get away with a pair of pliers
  • Safe connection with none leaks


  • Barely costly
  • Would possibly change into tough to take away the crimp connection for repairs
  • To be able to create a leak-proof seal, it’s worthwhile to apply lots of power

What’s PEX Clamp Connection?

Subsequent, we have now the PEX Clamp ring that’s made up of stainless-steel. It is usually referred to as Pinch Ring. It has a notch and visual jaws quite than a easy ring.

The process to make use of the sort of connection can also be much like the Copper Crimp ring. First, slide the Metal Clamp Ring over the pipe after which insert the tip of the PEX Pipe over the becoming. Then push the metal clamp over the connection.

Now comes the vital half. To be able to make the seal utilizing the metal clamp ring, you want a particular PEX Clamping Instrument or Pinching Instrument.

It’s a sort of ratcheting device that releases solely after making a superb seal (with a correct crimp of the metal ring). The device pinches the notch and, on this course of, the jaws of the ring clamp to the pipe and seal the connection.

Not like the copper crimp ring, which squeezes throughout the ring, the metal clamp ring solely applies power on the jaws of the ring.


  • Putting in and eradicating PEX Clamps is simple
  • You need to use it even in tight and awkward locations
  • Utilizing one PEX Clamp Instrument, you’ll be able to join metal clamps of various sizes
  • There’s a clear visible distinction between pinched and un-pinched clamp
  • No want for gauges
  • Metal Clamp Rings are sturdy and low-cost


  • The supply of Metal Clamp Rings and PEX Clamp Instruments was very uncommon. However issues are altering slowly
  • You want a particular pinching device or PEX Clamping device to make use of the metal clamp rings

PEX Crimp vs Clamp Connections

Now that we have now seen PEX Crimp and Clamp Connections allow us to go forward and make a comparability of PEX Crimp vs Clamp Connections.

1. Materials

PEX Crimp connections use Copper Rings whereas PEX Clamp connections use Stainless Metal rings. Other than copper, it’s also possible to get PEX Crimp rings in brass.
