Value Collection ZMSCV70018 Viton O-ring Dash 018 50pk

Product Description

The VALUE COLLECTION ZMSCV70018 is a Dash 018 Viton (fluoroelastomer) O-ring with a round cross section, sold in packs of 50. It measures 0.75 inches inside diameter, 0.875 inches outside diameter, and 0.0625 inches thick. Rated at 70 Shore A hardness, this O-ring handles a working temperature range of -15 degrees F to 400 degrees F, making it suited for high-heat and chemically aggressive service environments. Plumbers, HVAC technicians, and industrial mechanics use fluoroelastomer O-rings where standard nitrile or EPDM compounds fall short.

This O-ring is designed for sealing applications involving petroleum products, hydraulic fluids, and similar media. Its fluoroelastomer compound delivers low gas permeability and low compression set, which helps maintain a reliable seal under sustained pressure and temperature cycling. Typical installation scenarios include fluid fittings, valve stems, pump housings, and service port connections in HVAC, plumbing, and light industrial equipment where chemical compatibility and heat resistance are the primary selection criteria.

Key Features

• Fluoroelastomer (Viton) compound with wide-spectrum chemical compatibility
• Working temperature range: -15 degrees F to 400 degrees F
• 70 Shore A hardness rating for a firm, reliable seal
• Round cross section with low compression set for long service life
• Low gas permeability — suitable for vacuum service applications
• Good resistance to petroleum products and high-temperature media

Compatibility

Compatible with petroleum-based fluids and media. Designed as a standard Dash 018 O-ring replacement for fittings, valves, pumps, and connectors requiring a 0.75-inch ID fluoroelastomer seal.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or industrial mechanic. Depressurize and drain the system completely before removing the old O-ring or installing a new one. Inspect the groove and mating surfaces for nicks or contamination that could compromise the seal. Apply a compatible lubricant sparingly to ease installation and avoid rolling or twisting the O-ring during seating.
