Value Collection ZMSCH90217 O-ring Dash 217 Nbr

Product Description

The VALUE COLLECTION ZMSCH90217 is a Dash 217 O-ring made from Nitrile Butadiene Rubber (Buna-N), one of the most widely used elastomers in fluid sealing applications. It measures 1.188 inches inside diameter, 1.438 inches outside diameter, and 0.125 inches thick, with a round cross section. Rated at 90 durometer (extra hard), this O-ring delivers excellent compression set resistance along with strong tear and abrasion resistance. It is suited for use across a wide temperature range of -40 to 250 degrees F. Installation and maintenance technicians working on hydraulic, pneumatic, and mechanical assemblies will find this a reliable sealing solution.

This O-ring is used in residential and commercial applications involving petroleum-based fluids, hydraulic systems, pneumatic fittings, and general mechanical assemblies. Its Buna-N compound provides excellent resistance to petroleum products, making it a common choice in HVAC, plumbing, and industrial maintenance work. Sold in a package quantity of 50, it is well suited for shops and service fleets that replace O-rings regularly during equipment service and repair.

Key Features

• 90 durometer extra-hard rating for reliable compression set performance
• Operating temperature range: -40 to 250 degrees F
• Round cross section, Dash 217 standard sizing
• Meets SAE and MIL-Spec standards
• Package quantity of 50 units per order

Compatibility

Compatible with petroleum-based fluids and products. Designed as a standard Dash 217 O-ring replacement for use in hydraulic, pneumatic, and mechanical sealing applications where Buna-N material is specified. Not recommended for use with ozone-generating equipment or in direct sunlight storage conditions.

Installation Notes

O-rings of this type are installed by mechanics, plumbers, HVAC technicians, and industrial maintenance personnel. Always depressurize and power down the system before replacing any O-ring. Inspect the groove and mating surfaces for damage or debris before seating the new ring. Avoid overstretching the O-ring during installation, and do not store unused rings near motors, electrical equipment, or direct sunlight, as ozone exposure degrades Buna-N material.
