Value Collection ZMSCH90110 O-ring 0.375 in Id Nbr Dash 110

Product Description

The VALUE COLLECTION ZMSCH90110 is a Dash 110 O-ring manufactured from Nitrile Butadiene Rubber (Buna-N), the most widely used elastomer for fluid sealing in mechanical and fluid-handling applications. This O-ring measures 0.375 inches inside diameter, 0.563 inches outside diameter, and 0.094 inches thick with a round cross section. Rated at 90 durometer (extra hard), it delivers excellent compression set resistance along with strong tear and abrasion resistance. The temperature range of -40 to 250 degrees F makes it suitable for year-round service in a wide variety of static and dynamic sealing applications. HVAC technicians, plumbers, and mechanical contractors install this type of O-ring routinely during equipment assembly and repair.

This O-ring is designed for use in systems that handle petroleum-based fluids, hydraulic oils, and similar media. Typical applications include refrigeration service valves, HVAC compressor fittings, plumbing connections, pneumatic fittings, and general mechanical assemblies where a reliable, petroleum-resistant seal is required. The Dash 110 designation follows standard sizing conventions, making it straightforward to cross-reference against OEM specifications. It is not FDA approved and should not be used in direct food-contact applications. Sold in a package quantity of 100, it is well suited for shops and service fleets that maintain working stock of common O-ring sizes.

Compatibility

Compatible with petroleum products, hydraulic oils, and similar media. Designed as a standard Dash 110 O-ring replacement for static and dynamic sealing applications in HVAC, plumbing, pneumatic, and general mechanical systems. Not compatible with ozone, sunlight exposure over time, or motors and electrical equipment that generate ozone — store away from such sources.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or qualified mechanical technicians. Always depressurize and isolate the system before replacing an O-ring, and confirm the mating groove dimensions match the Dash 110 cross section before installation. Lightly lubricating the O-ring with a compatible fluid aids seating and reduces the risk of pinching or twisting during assembly. Do not store unused O-rings in direct sunlight or near motors or other equipment that generates ozone, as this degrades Buna-N elastomer over time.
