Value Collection ZMSCE70024 Epdm O-ring Dash 024 Pack 50

Product Description

The VALUE COLLECTION ZMSCE70024 is a Dash 024 EPDM O-ring engineered for sealing applications involving hot water, steam, and phosphate ester hydraulic fluids. It measures 1.125 inches inside diameter, 1.25 inches outside diameter, and 0.0625 inches thick, with a round cross section and a Shore A hardness rating of 70. Sold in a package of 50 pieces, this O-ring is suited for plumbing, HVAC, and hydraulic system maintenance tasks where EPDM's broad chemical and temperature resistance is required. Licensed trades and maintenance technicians typically specify EPDM in high-temperature water and steam service where nitrile or silicone compounds would degrade.

This O-ring is appropriate for residential and commercial plumbing systems, HVAC hydronic loops, steam distribution equipment, and aircraft-ground-support or industrial hydraulic systems that use phosphate ester fluids such as Skydrol. Its operating temperature range of -65 degrees F to 300 degrees F makes it a reliable choice for both sub-freezing cold-side service and high-temperature steam applications. Plumbers, HVAC technicians, and hydraulic system mechanics install this part during valve rebuilds, pump seal replacements, and fitting maintenance where a Dash 024 O-ring is specified.

Key Features

• EPDM compound provides excellent resistance to hot water, steam, and phosphate ester hydraulic fluids
• Rated for service from -65 degrees F to 300 degrees F
• Shore A hardness of 70 balances sealing compression with extrusion resistance
• Round cross section conforms to standard Dash 024 dimensional specifications
• Black color for easy visual identification during installation
• Packaged in quantities of 50 for shop stock and field service kits

Compatibility

Compatible with hot water, steam, and phosphate ester fluid systems. Designed as a standard Dash 024 EPDM O-ring replacement suitable for any application calling for that dash number and EPDM material. Not FDA approved; not recommended for food-contact or potable-water applications where food-grade certification is required.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or hydraulic system mechanic. Shut off and depressurize the system and allow it to cool before replacing any O-ring. Lightly lubricate the O-ring with a fluid compatible with EPDM compound before seating it in the groove to reduce the risk of tearing during assembly. Inspect the mating groove and sealing surfaces for corrosion or damage before installing the new ring.
