What are the leading plumbing fittings?
To get to the point, here are the specifics of the leading plumbing fittings :
- The copper fittings are brazed and require plumber's tools for their installation.
- The two- cone fittings allow seamless copper pipes to be connected.
- The screw fittings are screwed with Teflon or tow.
- The PEX fittings are part of a PEX installation and assemble seamlessly.
- The PVC fittings, pressure and evacuation, are to be bonded.
- The PE compression fittings are used on A234 WPB polyethylene pipe systems (main power); they are connected by screwing.
Plumbing installation is in 90% of copper cases, so you will have to use according to your skills and needs copper fittings, biconical fittings, screw fittings, and PVC fittings, which will most often be an evacuation.
Solder connection
Copper fitting
The A234 WP91 copper connectors are assembled by brazing to the copper pipes ( brazing is a welding technique). The brazing is for hot water and heating, while the cold soldering is intended for the cold water.

The soldering is carried out with a blowtorch or a welding lamp and a filler metal determined according to the metals to be brazed.
The Weld fittings are dimensioned to the diameter of the pipes and configured according to the needs of the installation (elbow, tee, sleeve, etc.).
Solderless connection
Screw connection
The screw fittings are no big surprise to screw. Their tightness is guaranteed by the application of Teflon or tow on their threads. Used in the home system, carbon steel pipe fittings are prepared of brass or stimulated and are obtainable in altered yarn sizes whose dimension is articulated in millimeters or inches. They are used as an elbow, tee, sleeve or plug and may require a seal.
Bicone or olive fitting
A bicone link permits two copper tube to be linked without brazing, but by coiling. It is the solution for a fast and efficient connection. Their operating principle: a ring deformed under the action of screwing tightens the respect of the fitting on the copper pipe. Perfect for having neither welding torch or torch.
PER connection
PER designates a material, crosslinked polyethylene, and the attachments make it possible to form a network. The PER is a flexible hose used in renovations in water and heating installations, its ease of installation (without soldering). These are two types of PER fittings: compression and automatic.
Compression fitting
This ASME B16.11 fasten certified by the devastating of the tube on the fitting. The crushing being carried out using a nut, a compression fitting, therefore, requires only a flat wrench of the right size to be mounted.
Automatic connection
Like the Stainless Steel 316 Pipe Fittings, the mechanical fitting does not require specialized knowledge or materials. The assembly is carried out thanks to a clip that is then locked using a nut. Very easy to assemble, it remains the least resistant of the PER fittings.
PVC evacuation fitting
The evacuation PVC denotes a PVC type, which is not designed to withstand any internal pressure; the flow, therefore, takes place by gravity. This type of PVC is found in the drain of sinks, showers, baths, and toilets.
stainless steel 304 pipe fittings are assembled by gluing ( special PVC glue ), thus ensuring a rigid and waterproof assembly.
