Gasket for cast-iron two-couplings EKO 2" TYCNER model 371

Gasket for cast-iron two-couplings EKO 2" TYCNER model 371 is a sealing element designed for use with 2-inch EKO cast-iron two-couplings. Manufactured to match the mating surfaces of cast-iron coupling halves, this gasket provides a compression seal that prevents leakage in pipeline and drainage assemblies. It is intended for installation during assembly, routine maintenance or replacement of worn seals in residential, commercial or light-industrial plumbing systems that use EKO two-couplings.

Advantages

This gasket matches the geometry of EKO 2" cast-iron two-couplings to ensure even compression and a reliable seal between coupling halves. Made from appropriate elastomer material for drainage and wastewater applications, it resists common contaminants encountered in cast-iron piping. The part is compact, easy to handle and designed for straightforward replacement without special tooling.

Suitable for

• Sealing 2" EKO cast-iron two-couplings in drainage and wastewater systems
• Routine maintenance and replacement of worn or damaged coupling seals
• Assembly of cast-iron pipeline sections where two-couplings are used
• Residential and commercial plumbing applications using EKO-style cast-iron connections

When it may not be suitable

This gasket is specifically shaped and dimensioned for 2" EKO cast-iron two-couplings; it may not fit or seal correctly with couplings of other standards, sizes or manufacturers. It is not intended as a universal gasket for all cast-iron or non-cast-iron connections and should not be used where the operating conditions exceed the chemical or temperature limits of the gasket material.

Key specifications

• Compatible connection size: 2-inch EKO two-couplings
• Application: cast-iron coupling sealing for drainage and pipeline assemblies
• Function: compression seal between coupling halves to prevent leakage
• Material type: elastomeric sealing material suitable for wastewater/drainage use
• Form: shaped gasket matching two-coupling geometry for even compression

How to use

Clean the mating surfaces of the cast-iron coupling halves to remove rust, debris and old seal remnants. Position the gasket so its profile aligns with the coupling grooves or faces, then bring the two coupling halves together evenly. Tighten the coupling clamps or bolts progressively and uniformly to achieve an even compression of the gasket, taking care not to overtighten. After assembly, inspect the joint for leaks under normal operating conditions and retighten if necessary following manufacturer torque guidance.

What to consider before purchase

• Verify that the gasket is compatible with 2" EKO cast-iron two-couplings used in your system
• Confirm the gasket material is suitable for the chemical and temperature conditions of your application
• Ensure the gasket profile matches the coupling geometry to achieve an effective seal

Usage recommendations

Store the gasket in a dry, cool place away from direct sunlight and ozone sources. Replace the gasket if it shows signs of cracking, permanent deformation or chemical degradation. When assembling, follow safe working practices for handling cast-iron pipes and use appropriate personal protective equipment.
