Mechanical Joint Gaskets & Gasket Packs (2"~48")

Mechanical Joint (MJ) Gaskets & Gasket Packs provide a dependable sealing solution for ductile iron piping systems across municipal waterworks, industrial, fire protection, and utility infrastructure. Available in sizes 2" through 48", these gasket sets are engineered to deliver long-lasting performance, leak-free joints, and consistent installation across both standard and transition mechanical joint connections.

 

Manufactured to ANSI/AWWA C111/A21.11 standards, MJ gaskets are available in SBR, NBR, and Viton materials to support a wide range of service conditions—from potable water and wastewater to oil, gas, and chemical environments. Complete gasket packs include premium Kor-10, extra-long, or anti-rotation T-bolts and nuts for a fully integrated installation solution.

 

These domestic gasket packs streamline procurement, simplify installation, and ensure system reliability—making them ideal for new construction, maintenance, and emergency repair work.

Standard Mechanical Joint Gasket Packs

Standard MJ gasket packs include an SBR gasket paired with Kor-10, extra-long, or anti-rotation T-bolts and nuts. Ideal for most waterworks, municipal, and utility installations, these packs provide consistent performance and easy assembly.

 

Transition Mechanical Joint Gasket Packs

Transition MJ gasket packs are engineered for joining differing pipe materials or sizes. Available with SBR gaskets and a choice of Kor-10, extra-long, or anti-rotation hardware, these packs ensure a reliable seal even in challenging alignment or dimensional conditions.

 

Material Options

SBR Mechanical Joint Gaskets

Best suited for potable water, wastewater, and general municipal applications.

NBR Mechanical Joint Gaskets

Recommended for installations exposed to oils, hydrocarbons, and industrial fluids.

Viton Mechanical Joint Gaskets

Ideal for high-temperature, chemical, or specialized industrial applications requiring superior resistance.

Hardware Options (Kor-10, Extra-Long, Anti-Rotation)

Engineered for durability, torque consistency, and long-term system reliability in MJ assemblies.
