How To Choose Your Plumbing Connection?

Indispensable for creating a water supply network in the home, plumbing fittings are used to assemble the supply pipes. They must be chosen according to the level of carbon steel fittings malaysia but also according to the piping used: multilayer, PER or copper. All our advice on choosing the fitting that will suit your needs.

PER fitting or multilayer fitting

It is a quick coupling (1) to install with a flaring pliers (2) then a sliding pliers (3). It is also very reliable. Ideal for a bathroom, a kitchen or a heating circuit.

The press fitting is the classic and durable solution par excellence, well suited to installation sites in new buildings.

Slide the multilayer pipe into the fitting 

(1) Until It Appears In The Inspection Window 

(2) Position The Jaw Of The Crimping Pliers 

(3) On The Fitting Nut And Firmly Close The Pliers To Crimp The Tube.

Ready to use, it is ideal for a small renovation site. The connector is assembled and disassembled by simple screwing. The tightness is perfectly assured.

It is sufficient to ensure that the adapter sleeve is fully engaged on the tube.

Fit the different parts on the body by tightening the cap by hand. Then push the tube all the way in until it stops. The advantage of this fitting is that it can be dismantled: unscrew the cap, remove the tube from the fitting and cut the clamping ring.

Copper or copper PER connection

With olive (or bicone washer) and without seal. Easy to install (without welding), it guarantees a perfect seal by metal-to-metal pressure effect: all you have to do is choose a nut adapted to the diameter of the tube.

The push-fit fitting (1) can be used without tools. Once deburred, the tube is simply pushed all the way into the fitting. This fitting can be used with all single-layer pipes (copper (2), PER (3), etc.). For the PER, a sleeve (4) is added inside the tube. A good solution for networks made of different.

Multilayer PER copper universal fitting

Universal copper-PER-multilayer fittings are ideal for renovation or for making an extension from a copper installation. They are screwed on with a simple open-end wrench and are as easy to install as they are reliable. Sealing by integrated O-rings guarantees a leak-free installation. The connection system is suitable for each type of pipe (PER, copper or multilayer). Standardized, it makes it possible to connect tubes of different materials.

The solutions

Universal Eurocone fittings allow you to connect a copper pipe with materials as different as PER or multilayer.

  • A system of adapters (one for each of the two materials to be connected) for a seamless connection.
  • Screwed with flat keys.
  • Provide integrated sealing.

Screw connection

The screw connections are usually brass or galvanized. Their main use is noted at the sanitary level.

The diameter of these fittings is very variable, with parts from 8 mm, and up to more than 30 mm.

To ensure a good seal, teflon or tow must be applied to the thread.

Before choosing a screw connection, it should be determined whether you need a male, a female, or a male-female assembly.

Welding connection

The solder connections are often copper or brass, with a very large diameter range from 10 to over 60 mm. We find solder fittings in both sanitary facilities and heating systems.

Crimp fitting

The press fittings can be copper, brass or bronze. These are fittings that allow installations with multilayer pipes to be made. You must always use a crimping pliers with inserts adapted to the diameter of the tube and the type of fittings.

Olive fitting

An olive fitting is also called a bicone fitting. It is in fact made of metal, with two truncated cones connected by the base which form an “olive”. For use only with rigid copper tubing.
