Value Collection ZMSCQH70219 O-ring Dash 219 Nbr Pack 50

Product Description

The VALUE COLLECTION ZMSCQH70219 is a Dash 219 X-profile (quattro cross section) O-ring made from nitrile butadiene rubber (NBR). It measures 1.313 inches inside diameter, 1.563 inches outside diameter, and 0.125 inches thick. The X-profile cross section provides four contact points instead of the two offered by a standard round-cross-section O-ring, improving sealing stability under dynamic and static conditions. NBR compound delivers solid resistance to petroleum-based fluids, hydraulic oils, and water, making this O-ring a reliable sealing solution for plumbing, HVAC, and fluid-system applications. Sold in a package of 50.

This O-ring is suited for use in static face-seal and low-speed dynamic seal applications where petroleum-based lubricants, water, or hydraulic fluids are present. Typical install scenarios include pump assemblies, valve bodies, hydraulic fittings, and fluid-line couplings found in commercial and residential plumbing, HVAC refrigerant-side components, and general industrial fluid systems. The NBR material performs across a broad service temperature range, making it appropriate for both indoor mechanical rooms and outdoor equipment enclosures.

Key Features

• X-profile (quattro) cross section provides four sealing contact points for improved stability versus standard round O-rings
• Nitrile butadiene rubber (NBR) compound resists petroleum-based oils, hydraulic fluids, and water
• Dash 219 standard sizing ensures dimensional interchangeability with other Dash 219 O-rings
• 1.313 inches ID and 1.563 inches OD with 0.125-inch thickness for precise groove fit
• Package of 50 units supports service-call inventory and bench-stock replenishment

Compatibility

Designed as an OEM-style replacement or service-stock O-ring for any application requiring a Dash 219 X-profile NBR O-ring with 1.313 inches inside diameter and 0.125 inches cross-section thickness.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or hydraulic system mechanics. Depressurize and drain the system completely before removing the old O-ring to prevent fluid release or injury. Lightly lubricate the O-ring with a compatible fluid or grease before seating it in the groove to avoid twisting or nicking during assembly. Inspect the mating groove for burrs or corrosion before installing a new O-ring.
