Value Collection ZMSCH70176 O-ring Dash 176 Nitrile Butadiene

Product Description

The VALUE COLLECTION ZMSCH70176 is a Dash 176 O-ring made from Nitrile Butadiene Rubber (Buna-N), the most widely used elastomer in sealing applications across HVAC, plumbing, fluid power, and general industrial systems. It measures 9.25 inches inside diameter, 9.438 inches outside diameter, and 0.0937 inches thick with a round cross section. Shore hardness is rated at 70, placing it in the hard range for reliable compression set and long service life under mechanical stress. This O-ring is installed by HVAC technicians, plumbers, and pipefitters wherever a dependable static or dynamic petroleum-compatible seal is required.

This O-ring suits a wide range of applications that involve petroleum-based fluids, hydraulic oils, fuels, and lubricants. Its Buna-N compound delivers strong resistance to petroleum products, making it a common choice for pump housings, valve bodies, manifolds, and fluid line fittings in both residential and commercial systems. The part meets SAE and MIL-Spec standards, supporting use in demanding mechanical and industrial environments. Package quantity is 25 units per order.

Compatibility

Compatible with petroleum products and petroleum-based fluids. Designed as an OEM-style replacement or service O-ring for any application requiring a Dash 176 Buna-N O-ring with a 9.25-inch inside diameter and 9.438-inch outside diameter. Not recommended for use with ozone-generating equipment or in direct sunlight storage conditions. Not FDA approved.

Installation Notes

Installation is performed by licensed HVAC technicians, plumbers, or pipefitters depending on the application. Always depressurize and drain the system before removing or installing O-rings to prevent fluid release or injury. Inspect the groove and mating surface for burrs, nicks, or contamination before seating the new O-ring. Avoid rolling or twisting the O-ring during installation, and do not store near motors or electrical equipment that may generate ozone, as ozone degrades Buna-N elastomers.
