Value Collection ZMSCE70217 Epdm O-ring Dash 217 50-pack

Product Description

The VALUE COLLECTION ZMSCE70217 is a Dash 217 EPDM O-ring designed for static and dynamic sealing applications where exposure to hot water, steam, and phosphate ester hydraulic fluids is expected. It measures 1.188 inches inside diameter, 1.438 inches outside diameter, and 0.125 inches thick with a round cross section. The compound carries a 70 Shore A hardness rating. EPDM formulation provides a wide service temperature range from -65 degrees F to 300 degrees F, making it a reliable choice for plumbing, HVAC hydronic systems, and industrial hydraulic circuits. Licensed plumbers, pipefitters, and HVAC technicians are the primary installers.

This O-ring is suited for residential and commercial hydronic heating systems, steam distribution lines, and hydraulic circuits using phosphate ester-based fluids such as Skydrol in commercial aircraft applications. The Dash 217 sizing is a standard AS568 dimension, commonly encountered in valve bodies, pump housings, pipe unions, and fitting connections across plumbing and mechanical systems. Each package contains 50 O-rings, providing enough quantity for production runs, maintenance kits, or service truck stock.

Key Features

• EPDM material rated for hot water and steam service up to 300 degrees F
• Cold-temperature rated to -65 degrees F for wide operating range
• 70 Shore A hardness provides firm compression sealing under pressure
• Round cross section conforms to standard AS568 Dash 217 dimensions
• Excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems
• Sold in a 50-piece package for service inventory and production use

Compatibility

Compatible with hot water, steam, and phosphate ester type hydraulic fluid systems. Designed as a standard AS568 Dash 217 replacement O-ring for use in valves, pumps, fittings, and mechanical connections requiring EPDM sealing material.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians. Always depressurize and drain the system before removing any fitting or valve that retains this O-ring. Inspect the gland groove for wear, corrosion, or debris before seating the new O-ring. Do not use petroleum-based lubricants with EPDM material; use a water-based or silicone-compatible assembly lubricant approved for EPDM compounds.
