Value Collection ZMSCH70162 O-ring Dash 162 Nbr 70 Duro

Product Description

The VALUE COLLECTION ZMSCH70162 is a Dash 162 Buna-N (Nitrile Butadiene Rubber) O-ring with a round cross section, sized at 5.75 inches inside diameter and 5.9380 inches outside diameter with a 0.0937-inch cross-section thickness. Rated at 70 Shore A hardness, this O-ring seals effectively in static and dynamic applications involving petroleum-based fluids. It operates across a wide service temperature range of -40 degrees F to 250 degrees F. Licensed plumbers, hydraulic technicians, and mechanical maintenance professionals install this part in fluid systems where petroleum-fluid compatibility is essential. Each order ships in a package quantity of 25 pieces.

This O-ring is suited for use in hydraulic systems, pneumatic assemblies, pumps, valves, pipe fittings, and fluid conveyance equipment where petroleum-product exposure is expected. The Dash 162 size designation makes it a standard reference across industrial, commercial plumbing, and mobile equipment platforms. Its Buna-N elastomer construction makes it one of the most broadly applied O-ring materials in the trade. Installation is common in both residential and commercial mechanical systems requiring reliable static face seals or low-pressure dynamic seals in oil, fuel, or hydraulic fluid environments.

Key Features

• Buna-N (Nitrile Butadiene Rubber) elastomer — excellent resistance to petroleum products, hydraulic oils, and fuels
• 70 Shore A hardness rated Hard — suitable for moderate-pressure sealing applications
• Round cross-section geometry — standard Dash 162 designation for drop-in replacement use
• Wide service temperature range: -40 degrees F to 250 degrees F
• Meets SAE and MIL-Spec standards
• Good tear and abrasion resistance with low compression set for long-term seal integrity

Compatibility

Designed as a standard Dash 162 O-ring replacement compatible with petroleum-based fluid systems, hydraulic assemblies, and plumbing applications that accept Buna-N elastomer seals. Compatible materials include petroleum products per manufacturer specification. Not FDA approved; not intended for use in food-grade or potable-water applications without independent verification.

Installation Notes

Plumbers, hydraulic technicians, and mechanical service professionals should de-pressurize and drain the system fully before replacing O-rings. Apply a compatible petroleum-based lubricant to the O-ring prior to installation to prevent rolling or tearing during seating. Avoid installing in direct contact with ozone sources such as electric motors or in prolonged direct sunlight exposure, which can degrade NBR elastomers. Follow applicable codes including IPC and relevant ASME or SAE standards for the service pressure and fluid type of the application.
