Plastic hoses



The plastic pipe is an excellent material for the installation of new pipework or the addition to an existing system. It is lightweight, joins more easily than metal and costs much less. You do not need a propane torch or expensive tools. Solvent cements and compression fittings create watertight, permanent and tight joints.

Plastic pipes have the same diameter as metal pipes. Special adapters and fittings connect plastic pipes to a metal system.

Chemically and electrically inert and smooth inside, so no rust, corrosive, accumulation of mineral deposits. No shoe read like metal.

Rigid and flexible varieties. What you buy depends on the plumbing code in your area and the function of the pipe and fittings must be used. Rigid pipes can be used for either sewage disposal (DWV) or for hot and cold water supply systems. Depending on the type of plastic. The hose is only for supply systems.

The rigid pipe is cut with a hacksaw and then glued with a solvent. Most codes specify that pipes and fittings of different plastics can not be mixed in the same system. The materials require different cements and grow at different speeds.

Flexible hoses are assembled with compression fittings rather than with solvent cements. The most flexible pipe, PB {polybutylene}, is used for hot and cold indoor systems. Excellent resistance to heat and very strong. But is usually more expensive than the rigid pipe.

Flexible hoses are suitable for remodeling where pipes must be snaked through walls, floors, ceilings and lawn irrigation systems. Although the hose is flexible, it can bend and bend only in gentle curves. It is rigid enough to support itself on quite long courses. But it is better to use additional media.
