Value Collection ZMSCVB75129 Viton O-ring Dash 129 25pk

Product Description

The VALUE COLLECTION ZMSCVB75129 is a Dash 129 Viton (fluoroelastomer) O-ring designed for static and dynamic sealing applications across HVAC, plumbing, and industrial fluid systems. It measures 1.563 inches inside diameter, 1.750 inches outside diameter, and 0.094 inches thick with a round cross section. The fluoroelastomer compound delivers a Shore A hardness of 75, low compression set, and broad chemical compatibility. The temperature range spans -15 degrees F to 400 degrees F, making it suitable for both high-temperature service and moderate cryogenic exposure. Each package contains 25 rings.

This O-ring is appropriate for use in petroleum-based fluid systems, hydraulic assemblies, fuel handling equipment, and vacuum service applications. Its low gas permeability and high temperature resistance make it a common choice for refrigerant circuit fittings, fuel line connections, and pump seals in both residential and commercial mechanical systems. Plumbers, HVAC technicians, and industrial maintenance professionals install this O-ring wherever a Dash 129 fluoroelastomer seal is specified.

Key Features

• Fluoroelastomer (Viton-type) material for high resistance to petroleum products and fuels
• Operating range of -15 degrees F to 400 degrees F suits high-temperature HVAC and fuel applications
• Shore A hardness of 75 with low compression set for long-term sealing integrity
• Low gas permeability makes it suitable for vacuum service
• Wide spectrum of chemical compatibility reduces the need for multiple seal types on a job
• Sold in a pack of 25 to support service inventory and reduce per-unit cost

Compatibility

Designed as a standard Dash 129 O-ring replacement compatible with systems that specify fluoroelastomer seals for use with petroleum products and high-temperature fluids.

Installation Notes

Installation should be performed by a qualified technician following applicable system codes such as IFGC or IPC where gas or fluid lines are involved. Always depressurize and isolate the system before removing any seals. Inspect the groove and mating surface for scoring or debris before seating the new O-ring. Do not use petroleum-based lubricants unless confirmed compatible with the system fluid; use an appropriate assembly lubricant rated for fluoroelastomer compounds.
