Value Collection ZMSCV70372 Viton O-ring Dash 372 2 Pack

Product Description

The VALUE COLLECTION ZMSCV70372 is a Dash 372 Viton (fluoroelastomer) O-ring with a round cross section, designed for static and dynamic sealing applications in demanding fluid and gas environments. It measures 8.75 inches inside diameter, 9.125 inches outside diameter, and 0.1875 inches thick. The 70-durometer hardness rating places it in the hard range, offering low compression set and resistance to deformation under sustained load. Fluoroelastomer construction provides broad chemical compatibility, high temperature resistance up to 400 degrees F, and low gas permeability. Each package contains 2 O-rings.

This O-ring is suited for use in HVAC, plumbing, hydraulic, and industrial fluid systems where exposure to petroleum products, high temperatures, or vacuum service is expected. The fluoroelastomer material handles a working temperature range of -15 degrees F to 400 degrees F, making it appropriate for both hot-side sealing in heating systems and chemically aggressive environments. Techs and tradespeople working with petroleum-based fluids, refrigerant oil circuits, or fuel-handling assemblies will find this size and compound combination appropriate for large-bore seal replacements.

Key Features

• Fluoroelastomer (Viton) compound with good resistance to petroleum products and fuels
• 70-durometer hardness rating for low compression set under sustained clamping load
• Operating range of -15 degrees F to 400 degrees F
• Low gas permeability makes it suitable for vacuum service
• Round cross section, Dash 372 standard sizing
• Package includes 2 O-rings per order

Compatibility

Designed as a standard Dash 372 O-ring replacement compatible with applications requiring fluoroelastomer seals rated for petroleum products and high-temperature service. Compatible materials include petroleum-based fluids and related compounds.

Installation Notes

Installation should be performed by a qualified technician familiar with the sealing system being serviced. Always depressurize and de-energize the system and relieve any fluid pressure before removing the old O-ring. Inspect the groove and mating surfaces for damage or debris before seating the new O-ring. Avoid twisting the O-ring during installation; use a compatible lubricant only if approved for fluoroelastomer and the process fluid involved.
