Value Collection ZMSCH2X16 O-ring 16in Id Nbr

Product Description

The VALUE COLLECTION ZMSCH2X16 is a Nitrile Butadiene Rubber (Buna-N) O-ring designed for static and dynamic sealing applications across plumbing, hydraulic, and mechanical systems. Measuring 16 millimeters inside diameter, 20 millimeters outside diameter, and 2 millimeters thick with a round cross section, this O-ring delivers a Shore A hardness of 70, placing it in the hard hardness range. Buna-N is the most widely used O-ring elastomer in the trade, valued for its excellent resistance to petroleum-based fluids, strong compression set performance, and solid tear and abrasion resistance. Licensed plumbers, pipefitters, hydraulic technicians, and mechanical service pros install this part.

This O-ring is suited for residential and commercial sealing applications involving petroleum products, hydraulic oils, fuels, and related fluids. It performs across a working temperature range of -40 degrees F to 250 degrees F, making it appropriate for a wide range of service environments. The round cross section is compatible with standard O-ring grooves in valves, fittings, cylinders, and pumps. It is not recommended for use with ozone-generating environments such as near electric motors, and should not be stored in direct sunlight.

Key Features

• Buna-N (Nitrile Butadiene Rubber) material with excellent resistance to petroleum products
• Shore A hardness of 70 for reliable sealing under compression
• Working temperature range: -40 degrees F to 250 degrees F
• Round cross section for standard O-ring groove fitment
• Meets SAE and MIL-Spec standards
• Sold in a package quantity of 100 with a minimum order quantity of 1

Compatibility

Compatible with petroleum products, hydraulic oils, and related fluid media. Designed as an OEM-style replacement O-ring for standard metric O-ring groove applications in valves, pumps, cylinders, and fittings.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or hydraulic technicians. Always depressurize and drain the system before removing or replacing O-rings. Inspect the mating groove for burrs or damage before seating the new O-ring. Do not store Buna-N O-rings near motors, ozone-generating equipment, or in direct sunlight, as ozone and UV exposure degrade nitrile rubber.
