Value Collection ZMSCQH70116 O-ring Dash 116 Nbr 100-pack

Product Description

The VALUE COLLECTION ZMSCQH70116 is a Dash 116 X-profile o-ring manufactured from Nitrile Butadiene Rubber (NBR), designed for static and dynamic sealing applications in fluid and pneumatic systems. The cross-section shape is quattro or X-profile rather than a standard round cross section, which provides four sealing contact points and improved stability in the groove. With a 70 Shore A durometer hardness rating, this o-ring delivers firm resistance to compression set and extrusion under moderate system pressures. It is sized at 0.75 inches inside diameter, 0.938 inches outside diameter, and 0.0937 inches thick, and is sold in a package quantity of 100 units.

This o-ring is suited for hydraulic, pneumatic, plumbing, and HVAC sealing applications where NBR material is compatible with the working fluid. NBR performs reliably with petroleum-based oils, fuels, water, and many common refrigeration oils. The X-profile design is a drop-in replacement in standard Dash 116 o-ring grooves. Typical installers include HVAC technicians, plumbers, and hydraulic system technicians working on pumps, valves, fittings, manifolds, and fluid connectors across residential and light commercial equipment.

Key Features

• X-profile (quattro) cross section provides four sealing contact points for improved groove stability over standard round o-rings
• Nitrile Butadiene Rubber material offers broad compatibility with petroleum oils, fuels, and water-based fluids
• 70 Shore A durometer provides firm resistance to extrusion and compression set
• Working temperature range of -30 degrees F to 250 degrees F suits most HVAC and plumbing service conditions
• Dash 116 sizing fits standard o-ring grooves machined to that designation
• Packed in quantities of 100, suitable for service stock and production use

Compatibility

Designed as a standard Dash 116 replacement o-ring for use in any application where an X-profile NBR seal of 0.75 inches inside diameter and 0.0937 inches thickness is specified. Not FDA approved; confirm fluid compatibility before installation in food-service or potable-water systems.

Installation Notes

Shut down and depressurize the system completely before removing or installing any sealing component. Lightly lubricate the o-ring with a compatible grease or fluid prior to seating to reduce installation stress and prevent nicking. Do not roll or twist the o-ring into the groove; seat it evenly around the full circumference. Verify the groove dimensions match Dash 116 specifications before installation to ensure proper compression and sealing.
