Value Collection ZMSCVB75118 Viton O-ring Dash 118

Product Description

The VALUE COLLECTION ZMSCVB75118 is a Dash 118 Viton fluoroelastomer O-ring designed for static and dynamic sealing applications across HVAC, plumbing, and industrial fluid systems. It measures 0.875 inches inside diameter, 1.063 inches outside diameter, and 0.094 inches thick, with a round cross-section and a durometer hardness rating of 75. The fluoroelastomer compound delivers high temperature resistance, low compression set, and broad chemical compatibility, making it a reliable choice for sealing against petroleum-based fluids, hydraulic media, and high-heat environments. Plumbers, HVAC technicians, and industrial maintenance professionals use this O-ring as a standard sealing component in fittings, valves, and connections.

This O-ring is suited for both residential and commercial service environments where elevated temperatures or petroleum product exposure would degrade standard nitrile or EPDM seals. Its operating range of -15 degrees F to 400 degrees F covers the thermal demands of hot water systems, refrigeration line components, fuel handling, and HVAC equipment. The brown fluoroelastomer compound also provides low gas permeability, making it appropriate for vacuum service and low-leakage sealing requirements. Sold in packages of 50, this item is practical for stocking service vehicles and shop inventory.

Key Features

• Fluoroelastomer (Viton-type) compound offers good resistance to petroleum products and wide chemical compatibility
• Operating temperature range: -15 degrees F to 400 degrees F for high-heat and cold-service applications
• 75 durometer hardness provides a firm, low-compression-set seal under sustained pressure
• Low gas permeability makes it suitable for vacuum service applications
• Round cross-section, Dash 118 sizing for direct replacement in standard O-ring grooves
• Package quantity of 50 supports bulk stocking and repeat service calls

Compatibility

Designed as a standard Dash 118 O-ring replacement compatible with applications involving petroleum products and hydraulic fluids. The fluoroelastomer compound is identified as compatible with petroleum-based media per supplier specifications.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or mechanical professional familiar with O-ring sealing systems. Shut off and depressurize the system completely before removing or replacing any sealing component. Inspect the mating groove for wear, scoring, or debris before seating the new O-ring. Do not use petroleum-based lubricants incompatible with the sealing media; consult system documentation for the appropriate assembly lubricant.
