Value Collection ZMSCE70332 Epdm O-ring Dash 332 Pack 10

Product Description

The VALUE COLLECTION ZMSCE70332 is a Dash 332 EPDM O-ring designed for use in fluid sealing applications where resistance to heat, steam, and specialty hydraulic fluids is required. It features a round cross-section with an inside diameter of 2.375 inches, an outside diameter of 2.75 inches, and a thickness of 0.1875 inches. Molded from ethylene propylene diene monomer (EPDM) compound at a 70 durometer hardness rating, this O-ring provides a firm, reliable seal under demanding service conditions. Each order ships in a package quantity of 10 pieces, making it suitable for maintenance stock and multi-unit repairs. Licensed trades and seal specialists working with hydraulic, plumbing, and mechanical systems rely on this profile for repeatable, consistent sealing performance.

This O-ring is well suited for hot water systems, steam applications, and phosphate ester type hydraulic fluid circuits. It also demonstrates excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems, making it a cross-industry solution. Typical installation scenarios include pipe flange sealing, valve bodies, pump housings, and hydraulic fittings where EPDM compound compatibility is specified. Plumbers, HVAC technicians, and mechanical contractors working on steam and hot water equipment will find this ring a direct fit for standard Dash 332 groove dimensions.

Compatibility

Compatible with hot water, steam, and phosphate ester hydraulic fluid systems. Also recommended for applications involving Skydrol fluids found in commercial aircraft hydraulic circuits. Designed to fit standard Dash 332 O-ring groove dimensions.

Installation Notes

Installation of O-rings should be performed by a qualified plumber, HVAC technician, or mechanical tradesperson familiar with sealing system requirements. Shut off and relieve pressure from the system before removing any fittings, valves, or flanges. Inspect the groove surface for nicks, burrs, or corrosion before seating the new ring, and apply a compatible lubricant to ease installation and reduce the risk of tearing. Never stretch the ring beyond the groove diameter or reuse a ring that shows signs of compression set, cracking, or deformation.
