Value Collection ZMSCH70MD214 O-ring Dash 214 Nbr 10-pack

Product Description

The VALUE COLLECTION ZMSCH70MD214 is a Dash 214 nitrile butadiene rubber (NBR) O-ring with a 1 inch inside diameter, 1.25 inch outside diameter, and a 0.125 inch round cross-section thickness. Rated for service from -40 degrees F to 250 degrees F, this O-ring is designed for use with petroleum-based fluids and is well suited for hydraulic, pneumatic, plumbing, and HVAC sealing applications. It carries a hard (70 Shore A) durometer rating, offering strong compression set resistance along with good tear and abrasion resistance. HVAC technicians, plumbers, and industrial maintenance professionals install this part as a face seal, piston seal, or static seal in fluid-handling systems.

This O-ring fits residential and commercial applications where a standard Dash 214 NBR seal is specified. Typical use cases include refrigerant service valves, hydraulic fittings, pump housings, and plumbing connections where petroleum-product compatibility is required. The round cross-section profile seats into standard Dash 214 grooves without modification. Each package contains 10 O-rings, making it practical to keep replacements on hand for routine maintenance and service calls. This item is not FDA approved for food-contact applications.

Compatibility

Designed as a standard Dash 214 O-ring replacement compatible with petroleum-product fluid systems. Suitable for use wherever a 1 inch ID, 1.25 inch OD, 0.125 inch cross-section NBR O-ring is specified. Not recommended for use with ozone, strong oxidizers, or ketone-based fluids. Store away from direct sunlight and ozone-generating equipment such as motors or electrical devices.

Installation Notes

Licensed plumbers, HVAC technicians, and qualified maintenance mechanics install this O-ring as part of routine seal replacement or system service. Before replacing an O-ring, shut off all fluid supply and relieve system pressure completely. Inspect the mating groove and sealing surfaces for scoring or contamination before seating the new ring. Avoid over-stretching the O-ring during installation, and use a compatible lubricant rated for NBR and the system fluid being sealed.
