Value Collection ZMSCH70914 O-ring Dash 914 Nbr 100 Pack

Product Description

The VALUE COLLECTION ZMSCH70914 is a Dash 914 O-ring boss gasket designed for use with straight-thread tube fittings. Made from Nitrile Butadiene Rubber (Buna-N), it measures 1.47 inches inside diameter, 1.279 inches outside diameter, and 0.116 inches thick with a round cross section. Rated at 70 Shore A hardness, this O-ring operates across a wide temperature range of -40 degrees F to 250 degrees F. Buna-N is the most widely used O-ring elastomer in fluid system applications, offering excellent resistance to petroleum-based media, strong compression set performance, and good tear and abrasion resistance. Each package contains 100 pieces.

This O-ring is suited for plumbing, hydraulic, and fluid power applications where petroleum-based fluids are present. The Dash 914 designation is a standard AN/SAE sizing used in hydraulic fittings, fuel systems, and pneumatic lines. It is installed by licensed plumbers, hydraulic technicians, and fluid system mechanics in both residential and light commercial settings. Typical applications include boss-port seal connections on straight-thread fittings found in HVAC refrigerant circuits, hydraulic manifolds, and fuel delivery systems.

Compatibility

Designed as an OEM-style replacement or service O-ring for straight-thread tube fittings using the Dash 914 boss gasket designation. Compatible with petroleum-based fluid media per SAE and MIL-Spec standards. Not FDA approved; not recommended for food, beverage, or ozone-exposed environments.

Installation Notes

Installation is performed by qualified plumbers, hydraulic technicians, or HVAC mechanics. Always depressurize and drain the system before removing or replacing O-rings. Lubricate the O-ring with a compatible petroleum-based or system-appropriate fluid prior to seating to avoid pinching or tearing. Do not store unused O-rings in direct sunlight or near motors and electrical equipment that may generate ozone, as ozone exposure degrades Buna-N elastomers.
