Value Collection ZBD9984-9 O-ring Dash 131 Nbr 1.69 in Id

Product Description

The VALUE COLLECTION ZBD9984-9 is a Dash 131 O-ring manufactured from Nitrile Butadiene Rubber (NBR) with a round cross section. It measures 1.69 inches inside diameter, 1.88 inches outside diameter, and 0.0937 inches (3/32 inches) thick. The durometer hardness rating is 70 Shore A, placing it in the hard range for NBR compounds. This O-ring is rated for a working temperature range of -40 degrees F to 275 degrees F, making it suitable for a wide range of fluid-sealing applications in HVAC, plumbing, and mechanical systems. Technicians and tradespeople use this part as a static or dynamic seal where petroleum-based fluid or air-system exposure is expected.

This O-ring fits applications that require a standard Dash 131 cross-section profile. It is commonly used in HVAC refrigeration fittings, plumbing valves, pump housings, and fluid-control assemblies where NBR compound compatibility with oils, fuels, and hydraulic fluids is required. The round cross section allows it to seat consistently in standard O-ring grooves machined to Dash 131 specifications. This part is sold individually, with a minimum order quantity of 25 units.

Compatibility

Designed for use in any application requiring a Dash 131 O-ring with NBR material, including HVAC fittings, plumbing valves, pump housings, and hydraulic or fluid-control assemblies where standard Dash 131 groove dimensions apply.

Installation Notes

Install this O-ring in a clean, dry groove free of nicks, burrs, or debris that could damage the sealing surface. Shut off fluid supply or system pressure completely before removing or installing seals. Lubricate the O-ring lightly with a compatible fluid or O-ring lubricant before seating to prevent twisting and tearing during assembly. Verify groove dimensions conform to Dash 131 specifications before installation to ensure proper compression and seal integrity.
