Pvc Rubber Coupling Underground

Fernco 3 in x 3 43 in dia shielded specialty coupling pvc fitting.

Pvc rubber coupling underground. No hub or shielded couplings can be used above or below ground because the shield provides extra strength to the coupling. Flexible rubber couplings are for use underground. For home use it comes in diameters ranging from 1 1 2 to 4 inches lengths are generally 8 or 12 feet long. Often referred to as fernco fittings after the name of a major manufacturer flexible neoprene and elastomeric pvc couplings are available in dozens of sizes and configurations.

Flexible transition couplings for underground piping systems. Item 792029 model p3000 33. They are also resistant to chemicals ultraviolet rays fungus growth and normal sewer gases due to the inert nature and physical properties of the pvc material. You should not replace a shielded no hub coupling with a flexible rubber coupling if it is an above ground installation or repair.

A slip coupler has no centre stop when lubricated it can be easily. The pipe sections are tough and durable and they join together using couplings primer and cement. They re designed for nonpressure drain waste and vent applications. 1 1 these specifications describe the properties of devices or assemblies suitable for use as flexible transition couplings hereinafter referred to as couplings for underground drainage and sewer piping systems.

So as it turns out these fittings are indeed rated for direct burial. Pvc underground drainage slip coupler. Made of tough elastomeric polyvinyl chloride pvc the flexible couplings are strong resilient and unaffected by soil conditions. Polyvinyl chloride or pvc pipe is used for both sewer and vent pipelines.
