Value Collection ZMSCH70104 O-ring Dash 104 Nbr Pack 100

Product Description

The VALUE COLLECTION ZMSCH70104 is a Dash 104 Nitrile Butadiene Rubber (NBR/Buna-N) O-ring used to create static and dynamic fluid seals in hydraulic, pneumatic, and plumbing systems. It features a round cross section measuring 0.125 inches inside diameter, 0.313 inches outside diameter, and 0.0937 inches thick. The durometer hardness is 70, placing it in the hard range for reliable compression set performance. Sold in a package of 100, this O-ring is a standard sealing component installed by plumbers, HVAC technicians, and mechanical service professionals across a wide range of fluid-handling applications.

The ZMSCH70104 is suited for use with petroleum-based fluids and oils, making it a practical choice in hydraulic systems, fuel-related assemblies, refrigeration service ports, and general-purpose plumbing connections. The Dash 104 designation follows the AS568 standard sizing series, allowing straightforward cross-reference to OEM specifications. It performs across a temperature range of -40 degrees F to 250 degrees F, covering most residential and light commercial service environments. Meets SAE and MIL-Spec standards.

Installation Notes

O-rings of this type are installed by licensed plumbers, HVAC technicians, and hydraulic system mechanics. Always relieve system pressure and depressurize the line or component before replacing an O-ring. Lightly lubricate the O-ring with a compatible fluid or O-ring lubricant before seating to prevent cutting or rolling during assembly. Inspect the seating groove for burrs or damage before installation.
