Value Collection ZMSCQH70325 O-ring Dash 325 Nbr 25-pack

Product Description

The VALUE COLLECTION ZMSCQH70325 is a Dash 325 O-ring with an X-profile cross section, manufactured from Nitrile Butadiene Rubber (NBR). It measures 1.5 inches inside diameter, 1.875 inches outside diameter, and 0.1875 inches thick. The four-lobed X-profile cross section reduces spiral twist and rolling in dynamic groove applications compared to standard round-section O-rings. NBR compound provides reliable resistance to petroleum-based oils, hydraulic fluids, and water, making this seal a common choice across plumbing, hydraulic, and fluid-handling assemblies. Licensed plumbers, HVAC technicians, and industrial maintenance professionals install this type of seal in both static and dynamic face-seal or radial-groove applications.

This O-ring is suited for use in residential and light commercial plumbing fittings, hydraulic valve bodies, pump housings, and fluid-transfer manifolds where a Dash 325 standard-size seal is specified. The NBR material performs well in systems carrying petroleum oils, water, and common aqueous solutions. The X-profile is particularly useful in low-squeeze groove designs where a conventional round O-ring might roll or displace during assembly or cyclic pressure events. Sold in a package of 25, this listing is appropriate for service shops and field technicians who stock common seal sizes.

Key Features

• Dash 325 standard sizing for straightforward replacement and groove compatibility
• Nitrile Butadiene Rubber compound resists petroleum oils, hydraulic fluids, and water
• 1.5 inches ID x 1.875 inches OD x 0.1875 inches thick for precise groove fit
• Package of 25 units supports bench-stock and field service kit restocking

Compatibility

Designed as a standard Dash 325 replacement O-ring for static and dynamic seal grooves in plumbing fittings, hydraulic assemblies, pump housings, and fluid-handling components that specify a 1.5 inches ID x 1.875 inches OD x 3/16 inches thick X-profile NBR seal.

Installation Notes

De-pressurize and isolate the system before removing the existing seal. Clean the groove thoroughly and inspect for wear, burrs, or corrosion before installing the new O-ring. Apply a compatible lubricant to the O-ring and groove to ease installation and prevent nicking or tearing during assembly. Do not overstretch the O-ring when seating it, as permanent deformation will compromise the seal.
