What is an MJ gasket?

The Mechanical Joint (MJ) gasket is designed to be used in Ductile iron mechanical joint pipe and fittings. MJ gaskets are typically supplied as Styrene Butadiene Rubber (SBR) and can be used for water and domestic sewage service. MJ gaskets made from SBR are used for air or liquid temperatures up to 150°F.

What is a MJ transition gasket?

The MJ X IPS Transition gasket is designed to be used in cast iron mechanical joint fittings for adapting to PVC or steel pipe (IPS dimensions). These gaskets made of SBR are usually used for water and domestic sewage service.

What are MJ fittings used for?

The standard defines “mechanical joint” as: “a joint in which a positive seal is achieved when a gasket is compressed by means of a mechanical device.” A mechanical-joint (MJ) connection is the most common method used to join PVC pipe to a valve or an iron fitting.

What are MJ couplings?

The Mechanical Joint (MJ) Coupled Joint offers a method of providing joint restraint with a standard mechanical joint socket of a pipe, fitting, valve or other product.

What is a MJ coupling?

Shielded Mechanical joint (MJ) or no hub couplings connect Cast Iron hubless soil pipe and fittings in sanitary and drain waste and vent (DWV) applications. For non-pressure, gravity flow applications only. Recommended for above and underground installations. Easy to install and reuse.

What is MJ in plumbing?

MJ stands for Mechanical Joint. It is a type of compression joint designed for underground connection for pipe, valves and fittings.

What is a Megalug?

The Series 1100 MEGALUG® Mechanical Joint Restraints effectively and economically restrain Ductile Iron Pipe (DIP) to mechanical joints above or below ground, for practically any application including valves, hydrants, and pipe.

What is the difference between a gasket and a flange?

Gaskets seal a connection between two components or flanges that have flat surfaces, while seals are used between engine parts, pumps, and shafts that rotate. Gaskets are used wherever a union or flange is required to prevent leaking.
