Value Collection ZMSCQH70326 O-ring Nbr Dash 326

Product Description

The VALUE COLLECTION ZMSCQH70326 is a Dash 326 nitrile butadiene rubber (NBR) O-ring with an X-profile cross section, also known as a quad ring or Quattro ring. It measures 1.625 inches inside diameter, 2.0 inches outside diameter, and 0.1875 inches thick. The four-lobed X cross section provides improved sealing contact compared to a standard round cross section, reducing spiral twist and roll in dynamic applications. NBR compound offers solid resistance to petroleum-based fluids, oils, and hydraulic media, making this ring a practical choice for plumbing, HVAC, and fluid-system sealing tasks. Licensed tradespeople and mechanical contractors stock these for routine maintenance and repair work.

This O-ring is suited for static face seals, static radial seals, and light dynamic applications where NBR chemical compatibility is appropriate. Typical installations include hydraulic fittings, pump housings, valve bodies, and refrigerant-side connections that accept NBR. The X-profile geometry makes it a direct functional replacement for standard round-section O-rings in the same Dash 326 groove dimensions. Each package contains 25 rings, supporting shop stock or service-van inventory needs.

Key Features

• X-profile cross section reduces spiral twist and roll in dynamic sealing grooves
• Nitrile butadiene rubber (NBR) compound for compatibility with petroleum-based oils and hydraulic fluids
• Dash 326 standard sizing for straightforward groove-dimension matching
• 1.625 inches ID and 2.0 inches OD for precise fitment in standard Dash 326 applications
• 0.1875 inches thickness provides consistent squeeze and sealing force in standard groove depths
• Sold in packages of 25 to support shop stock or multi-unit service calls

Compatibility

Designed as an OEM-style replacement or service-stock O-ring for any application calling out a Dash 326 cross-section dimension in NBR material.

Installation Notes

Plumbers, HVAC technicians, and hydraulic system technicians install this O-ring. Always depressurize and drain the system before replacing seals, and confirm that all residual fluid has cleared the work area. Lubricate the O-ring with a compatible fluid or grease before seating to prevent tearing during assembly. Verify that the groove dimensions match Dash 326 specifications before installation to ensure proper compression and seal integrity.
