Value Collection ZMSCV70038 Viton O-ring Dash 038 Pack of 10

Product Description

The VALUE COLLECTION ZMSCV70038 is a Dash 038 Viton fluoroelastomer O-ring designed for sealing applications that demand high temperature resistance and broad chemical compatibility. With a 2.625-inch inside diameter, a 2.75-inch outside diameter, and a cross-section thickness of 0.0625 inches, this O-ring fits standard Dash 038 groove dimensions. Rated to 400 degrees F maximum and -15 degrees F minimum, the fluoroelastomer compound delivers low compression set and low gas permeability. It is sold in a package of 10 and is the correct choice wherever petroleum-based fluids, high heat, or vacuum service are factors in the sealing environment.

This O-ring is suited for HVAC, refrigeration, plumbing, and industrial fluid-system applications where standard rubber compounds fall short. Typical uses include pump seals, valve stems, compressor fittings, and hydraulic connections exposed to petroleum products or elevated operating temperatures. The fluoroelastomer material provides a wide spectrum of chemical compatibility, making it a reliable choice for both residential and light commercial service work. Plumbers, HVAC technicians, and industrial maintenance professionals routinely use Dash 038 O-rings as replacement seals during component service or overhaul.

Key Features

• Fluoroelastomer (Viton-type) compound rated from -15 degrees F to 400 degrees F
• Dash 038 sizing: 2.625 inches ID, 2.75 inches OD, 0.0625 inches thick
• Round cross-section profile for consistent groove seating and uniform compression
• Low compression set for long-term sealing integrity under sustained load
• Good resistance to petroleum products and compatible with a wide range of chemicals
• Suitable for vacuum service due to low gas permeability

Compatibility

Designed as a standard Dash 038 replacement O-ring compatible with applications involving petroleum products and requiring high temperature resistance up to 400 degrees F. Confirm groove dimensions before installation.

Installation Notes

Power down or depressurize the system completely before replacing any O-ring seal. Inspect the mating groove and sealing surface for nicks, corrosion, or debris that could compromise the new seal. Lubricate the O-ring lightly with a compatible fluid or grease before seating to prevent tearing during assembly. Installation should be performed by a qualified tradesperson following applicable code requirements such as NEC, IPC, or IFGC depending on the system type.
