Value Collection ZMSCQH70226 Nbr O-ring Dash 226 2 in Id

Product Description

The VALUE COLLECTION ZMSCQH70226 is a Dash 226 X-profile O-ring made from Nitrile Butadiene Rubber (NBR), sized at 2.0000 inches inside diameter, 2.2500 inches outside diameter, and 0.1250 inches thick. The quattro cross-section shape provides four sealing lobes rather than a traditional round cross-section, improving stability in the groove and reducing spiral twist under dynamic movement. Rated for a temperature range of -30 degrees F to 250 degrees F with a Durometer Shore A hardness of 70, this O-ring suits fluid and pneumatic sealing applications common in HVAC, plumbing, and industrial fluid systems. It is sold in packs of 10 and is not FDA approved.

This O-ring is appropriate for use in residential and commercial sealing applications where NBR compatibility with petroleum-based fluids, water, and moderate hydraulic oils is required. The Dash 226 sizing is a standard AS568 dimension, making it a direct-fit replacement in any groove engineered to that spec. Typical install scenarios include pump housings, valve stems, pipe unions, and fluid connectors found in HVAC refrigerant-adjacent assemblies, plumbing shutoffs, and pool and spa equipment. Installers in all four trades will encounter this dash size in field service.

Key Features

• X-profile (quattro) cross-section reduces spiral twist and improves groove retention compared to standard round-section O-rings
• NBR material provides strong resistance to petroleum-based fluids, water, and mild hydraulic oils
• Dash 226 standard AS568 sizing ensures drop-in fitment in any groove machined to that specification
• Durometer Shore A 70 hardness balances flexibility and compression resistance for static and dynamic seals
• Rated operating range of -30 degrees F to 250 degrees F covers most HVAC and plumbing service conditions
• Sold in a pack of 10 for multi-unit service calls or stock replenishment

Compatibility

Designed as a standard Dash 226 replacement O-ring for any assembly using AS568-226 groove dimensions with an X or quattro cross-section profile in NBR material.

Installation Notes

Shut off and depressurize the system fully before removing the old O-ring. Lightly lubricate the O-ring with a compatible fluid or O-ring grease before seating it in the groove to prevent tearing during installation. Do not use petroleum-based lubricants with O-ring materials that are not petroleum-compatible. Follow applicable plumbing or mechanical codes (IPC, IFGC) for pressure system reassembly and leak testing after service.
