Value Collection ZMSCE70222 Epdm O-ring Dash 222 Pack 50

Product Description

The VALUE COLLECTION ZMSCE70222 is a Dash 222 EPDM O-ring designed for static and dynamic sealing applications in plumbing, HVAC, and industrial fluid systems. It measures 1.5 inches inside diameter, 1.75 inches outside diameter, and 0.125 inches thick, with a round cross section. The material is Ethylene Propylene Diene Monomer (EPDM) with a hardness rating of 70 Shore A. EPDM compound delivers strong resistance to hot water, steam, and phosphate ester hydraulic fluids, making this O-ring a reliable choice for service technicians working on hydronic systems, steam lines, and hydraulic circuits. Each package contains 50 pieces.

This O-ring is suited for residential and commercial applications involving hot water distribution, steam service, and phosphate ester type hydraulic fluid systems. It also carries noted resistance to Skydrol fluids used in commercial aircraft hydraulic systems, broadening its use across industrial and aviation maintenance work. Plumbers, HVAC technicians, and industrial maintenance professionals will encounter this size in valve bodies, pump flanges, pipe unions, and manifold connections where a reliable EPDM seal is required at elevated temperatures.

Key Features

• EPDM construction rated for service from -65 degrees F to 300 degrees F
• 70 Shore A hardness rating provides a firm, durable seal under compression
• Round cross section for consistent seating in standard O-ring grooves
• Excellent resistance to hot water, steam, and phosphate ester hydraulic fluids
• Noted resistance to Skydrol fluids used in commercial aircraft hydraulic systems
• Sold in a 50-piece package to support stocking and repeat-service needs

Compatibility

Designed for sealing applications compatible with hot water, steam, and phosphate ester hydraulic fluid media. Suitable for use in standard Dash 222 O-ring grooves across plumbing, HVAC, and industrial fluid handling equipment.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified maintenance professional. Isolate and depressurize the system and allow all components to cool before replacing any O-ring. Inspect the mating groove for debris, corrosion, or damage before seating the new O-ring. Do not use petroleum-based lubricants with EPDM compound; use a compatible water-based or silicone-based assembly lubricant only.
