Value Collection ZMSCH70113 O-ring Dash 113 Buna-n 70A Pack 100

Product Description

The VALUE COLLECTION ZMSCH70113 is a Dash 113 O-ring manufactured from Nitrile Butadiene Rubber (Buna-N), the most widely used elastomer in fluid sealing applications. It measures 0.563 inches inside diameter, 0.750 inches outside diameter, and 0.0937 inches thick with a round cross section. Rated at 70 Shore A hardness, this O-ring delivers reliable compression set resistance, strong tear and abrasion resistance, and excellent compatibility with petroleum-based fluids. It is suited for static and dynamic sealing in plumbing, HVAC, hydraulic, and pneumatic assemblies. Licensed plumbers, HVAC technicians, and maintenance mechanics install this part in a wide range of service and repair scenarios. Sold in a package of 100.

This O-ring is designed for use in systems handling petroleum-based products, oils, fuels, hydraulic fluids, and similar media. It performs across a wide service temperature range of -40 degrees F to 250 degrees F, making it appropriate for both low-ambient outdoor installations and moderate-temperature fluid circuits. The Dash 113 designation conforms to standard AS568 sizing, ensuring dimensional interchangeability in any application that calls for a Dash 113 seal. Typical install locations include valve stems, union fittings, pump housings, manifold ports, and compression fittings in residential and light commercial mechanical systems.

• Pack of 100 units minimizes downtime during multi-point service calls

Compatibility

Compatible with petroleum products, oils, hydraulic fluids, and similar media. Designed as a standard Dash 113 O-ring replacement for any application requiring a 0.563 inch ID by 0.750 inch OD by 0.0937 inch thick round-cross-section seal. Not FDA approved; not recommended for food-grade or potable-water-contact applications.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Always depressurize the system and isolate fluid supply before removing existing seals. Inspect the groove or port bore for nicks, burrs, or corrosion that could damage the new O-ring during seating. Do not store Buna-N O-rings in direct sunlight or near motors and other electrical equipment that may generate ozone, as ozone exposure degrades nitrile elastomers.
