Value Collection ZMSCH2.5X17 Nitrile O-ring 17mm

Product Description

The VALUE COLLECTION ZMSCH2.5X17 is a round cross-section nitrile butadiene rubber (Buna-N) O-ring designed for fluid and pneumatic sealing applications across a wide range of industrial and trade environments. With a 17 mm inside diameter, 22 mm outside diameter, and 2.5 mm thickness, this O-ring delivers reliable static and dynamic sealing performance. Rated for temperatures from -40 degrees F to 250 degrees F, it handles thermal cycling common in HVAC, plumbing, and hydraulic systems. A Shore hardness of 70 provides firm compression set resistance while maintaining effective sealing under pressure.

This Buna-N O-ring is suited for applications involving petroleum-based fluids, hydraulic oils, fuels, and general-purpose sealing in residential and commercial mechanical systems. It is commonly installed by HVAC technicians, plumbers, and industrial maintenance professionals during equipment servicing, valve replacement, and pump rebuilds. The black Buna-N compound is the most widely used O-ring elastomer in the trades and is appropriate for a broad range of fluid-handling environments where petroleum product compatibility is required.

Key Features

• Buna-N (nitrile butadiene rubber) construction with excellent resistance to petroleum products
• Round cross-section profile for reliable static and dynamic sealing
• Rated from -40 degrees F to 250 degrees F operating temperature range
• Shore hardness of 70 for strong compression set and abrasion resistance
• 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 and petroleum-based fluids. Designed for use as a general-purpose sealing O-ring in hydraulic, pneumatic, plumbing, and HVAC applications where Buna-N elastomer is specified. Not FDA approved; not recommended for applications requiring food-grade or ozone-rich environments.

Installation Notes

Installation should be performed by a qualified technician familiar with sealing component replacement in the relevant system type. Always depressurize and de-energize the system before removing or installing O-rings. Avoid stretching the O-ring beyond its designed limits during installation, and do not store near direct sunlight, electric motors, or other ozone-generating equipment, as ozone exposure degrades nitrile rubber. Lubricate with a compatible petroleum-based or system-appropriate lubricant prior to seating.
