Value Collection ZBD9984-24 O-ring Dash 147 Nbr 2.69 in Id

Product Description

The VALUE COLLECTION ZBD9984-24 is a Dash 147 O-ring designed for static and dynamic sealing applications across plumbing, HVAC, and fluid-handling systems. Molded from Nitrile Butadiene Rubber (NBR) with a Shore A hardness of 70, it measures 2.69 inches inside diameter, 2.88 inches outside diameter, and 0.0937 inches thick with a round cross section. NBR compound delivers reliable resistance to petroleum-based oils, fuels, and hydraulic fluids. The operating temperature range runs from -40 degrees F to 275 degrees F, making it suitable for a broad range of mechanical and fluid system service conditions. Plumbers, HVAC technicians, and industrial maintenance trades install this type of seal during equipment rebuilds, pump service, and valve maintenance.

This O-ring fits sealing grooves dimensioned to the Dash 147 standard. Typical applications include pump housings, valve bodies, pipe fittings, compressor end caps, and hydraulic manifolds where a 2.69-inch ID seal is specified. The NBR compound is well suited for water, refrigeration oils, and hydrocarbon-based fluids but is not recommended for exposure to ozone, strong acids, ketones, or esters. This part is sold individually with a minimum order quantity of 25 units.

• Nitrile Butadiene Rubber (NBR) construction resists petroleum oils, fuels, and hydraulic fluids
• Shore A hardness of 70 for a firm, reliable seal under compression
• Wide service temperature range: -40 degrees F to 275 degrees F
• Round cross section for consistent groove fit and even compression load
• Minimum order quantity of 25 units suits field stocking and bulk service kit builds

Compatibility

Designed as an OEM-style replacement or service seal for any equipment specifying a Dash 147 O-ring with a 2.69-inch inside diameter and NBR compound.

Installation Notes

Power down or depressurize the system completely before removing the old seal. Clean the groove of debris, old sealant, and residual compound before seating the new O-ring. Apply a thin film of compatible lubricant to the O-ring prior to assembly to prevent tearing during installation. Verify groove dimensions against Dash 147 tolerances before use; installing an O-ring in an improperly sized groove will compromise the seal.
