Value Collection ZMSCE70134 Epdm O-ring Dash 134 50-pack

Product Description

The VALUE COLLECTION ZMSCE70134 is a Dash 134 EPDM O-ring designed for static and dynamic sealing applications in fluid and steam systems. Manufactured from Ethylene Propylene Diene Monomer (EPDM), this O-ring carries a 70 Shore A hardness rating and a round cross section. It measures 1.875 inches inside diameter, 2.063 inches outside diameter, and 0.094 inches thick. The operating temperature range spans -65 degrees F to 300 degrees F, making it well suited for hot water, steam, and phosphate ester hydraulic fluid service. Plumbers, HVAC technicians, and industrial maintenance professionals install these seals in equipment where EPDM chemical compatibility is a requirement.

This O-ring is appropriate for residential and commercial plumbing, hydronic heating systems, steam lines, and hydraulic circuits using phosphate ester fluids such as those found in commercial aircraft ground support and industrial equipment. EPDM compound provides excellent resistance to hot water and steam environments where nitrile or neoprene seals would degrade prematurely. Each order is sold in a package quantity of 50 pieces, which suits bench stock replenishment and service van inventory needs. The material is not FDA approved, so it is not intended for food-contact or potable water applications where FDA compliance is required.

Key Features

• EPDM compound rated for hot water, steam, and phosphate ester hydraulic fluids
• 70 Shore A hardness for reliable sealing under compression

• Round cross section, Dash 134 standard sizing
• Sold in a 50-piece package for efficient stock replenishment
• Black color for easy visual identification in the field

Compatibility

Compatible sealing applications include hot water systems, steam service, and phosphate ester type hydraulic fluids. This O-ring is not recommended for petroleum-based oils, fuels, or food-contact service. Verify groove dimensions against Dash 134 specifications before installation.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified industrial maintenance technician. Depressurize and drain the system fully before removing the old seal and installing the replacement O-ring. Lubricate the O-ring with a fluid compatible with EPDM prior to seating it in the groove to prevent twisting or pinching during assembly. Do not use petroleum-based lubricants, as they will degrade EPDM compound.
