Value Collection ZBDMP9994 O-ring Dash 325 Nbr 1.5 in Id

Product Description

The VALUE COLLECTION ZBDMP9994 is a Dash 325 O-ring used to create fluid-tight seals in hydraulic, pneumatic, plumbing, and mechanical systems. It measures 1.5 inches inside diameter, 1.88 inches outside diameter, and 0.1875 inches thick with a round cross section. Constructed from Nitrile Butadiene Rubber (NBR) with a Shore A hardness of 70, it resists oils, fuels, and hydraulic fluids across a wide service temperature range. Plumbers, HVAC technicians, and industrial maintenance professionals install this O-ring as a static or dynamic seal in fittings, valves, pumps, and manifolds where petroleum-based fluid compatibility is required.

This O-ring is suited for residential and light commercial plumbing, HVAC refrigerant circuits, hydraulic assemblies, and general industrial applications. Its NBR compound performs reliably in environments with exposure to petroleum oils, mineral-based hydraulic fluids, water, and many common refrigerants. The Dash 325 designation is a standard AS568 size, making it a straightforward drop-in for any equipment specifying a Dash 325 O-ring. Sold individually per package with a minimum order quantity of 10 units.

Installation Notes

Power down or depressurize the system and relieve all fluid pressure before removing the old O-ring or installing a replacement. Clean the groove and mating surfaces thoroughly to remove debris, old sealant, or damaged material before seating the new O-ring. Apply a light coat of compatible lubricant to the O-ring prior to installation to prevent tearing during assembly. Installation should follow applicable plumbing, mechanical, or equipment manufacturer guidelines for O-ring sealing applications.
