Value Collection ZMSCH2X9 Buna-n O-ring 9mm Id 13mm Od

Product Description

The VALUE COLLECTION ZMSCH2X9 is a round cross-section O-ring made from Buna-N (Nitrile Butadiene Rubber), one of the most widely used elastomers in fluid sealing applications. With a 9 mm inside diameter, 13 mm outside diameter, and 2 mm thickness, this O-ring delivers reliable static and dynamic sealing performance. The black Buna-N compound offers excellent resistance to petroleum-based fluids, strong compression set characteristics, and solid tear and abrasion resistance. Hardness is rated at 70 Shore A. Operating temperature range spans from -40 degrees F to 250 degrees F. Sold in a package of 100 pieces.

This O-ring is suited for use in hydraulic systems, pneumatic assemblies, fluid transfer lines, and mechanical seals where petroleum-based media are present. Common install scenarios include pump seals, valve stems, cylinder heads, and fittings in industrial, plumbing, and fluid power applications. The small metric profile makes it appropriate for compact fittings and precision assemblies encountered in both light industrial and trade service work. This product is not FDA approved and should not be stored in direct sunlight or near motors and other electrical equipment that may generate ozone.

Key Features

• Round cross section ensures consistent seating and uniform compression in standard O-ring grooves
• 70 Shore A hardness rating suited for general-duty sealing under moderate pressure
• Wide service temperature range: -40 degrees F to 250 degrees F
• Meets SAE and MIL-Spec standards
• Packaged in quantities of 100 for shop stock and service fleet use

Compatibility

Compatible with petroleum-based products and fluids. Designed as a standard metric O-ring replacement for hydraulic, pneumatic, and fluid sealing applications requiring a 9 mm ID, 13 mm OD, 2 mm thick round cross-section seal.

Installation Notes

O-ring installation should be performed by a qualified mechanic, plumber, or fluid systems technician. Always depressurize and drain the system before removing any seals or fittings. Lightly lubricate the O-ring with a compatible fluid prior to seating to prevent pinching or tearing during assembly. Do not overstretch the O-ring during installation, and inspect the groove for nicks or burrs that could compromise the seal.
