Value Collection ZMSCE70336 O-ring Dash 336 Epdm 70

Product Description

The VALUE COLLECTION ZMSCE70336 is an EPDM O-ring with a round cross section, sized to Dash 336 specifications with a 2.875-inch inside diameter, 3.25-inch outside diameter, and 0.1875-inch thickness. Molded from ethylene propylene diene monomer (EPDM) compound at a Shore A hardness of 70, this O-ring delivers a firm, resilient seal. It is rated for service from -65 degrees F to 300 degrees F, making it suitable for elevated-temperature fluid systems. Plumbers, HVAC technicians, and industrial maintenance professionals install this type of seal in piping assemblies, valve bodies, and fluid-system fittings where a durable, chemical-resistant static or dynamic seal is required.

This O-ring is suited for use with hot water, steam, and phosphate ester hydraulic fluids. It also demonstrates excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems, making it a recognized choice for aerospace ground-support and aviation maintenance applications in addition to standard plumbing and HVAC service. It is not FDA approved and should not be used in food-contact or potable-water applications without independent verification of compliance requirements.

Compatibility

Designed as an OEM-style replacement or service seal for fluid systems requiring a Dash 336 EPDM O-ring; compatible with hot water, steam, and phosphate ester type hydraulic fluid applications.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Always depressurize and isolate the fluid system before removing the existing seal. Inspect the O-ring groove for wear, scoring, or contamination before seating the new ring. Avoid twisting or overstretching the O-ring during installation, as deformation can compromise the seal.
