Value Collection ZMSCVB75027 Viton O-ring Dash 027

Product Description

The VALUE COLLECTION ZMSCVB75027 is a Dash 027 Viton (fluoroelastomer) O-ring designed for static and dynamic sealing applications across HVAC, plumbing, hydraulic, and industrial fluid systems. It measures 1.313 inches inside diameter, 1.438 inches outside diameter, and 0.0625 inches (1/16 inch) thick with a round cross section. The compound is rated at 75 Shore A durometer, placing it in the hard hardness range for firm seating and low compression set. Operating temperature range spans -15 degrees F to 400 degrees F, making it suitable for high-heat service environments where standard buna-N compounds would degrade.

This O-ring is commonly used in petroleum product systems, hydraulic fittings, fuel handling components, and vacuum service lines. Its fluoroelastomer base material delivers broad chemical compatibility and low gas permeability, which is a critical requirement for refrigerant circuit seals, fuel solenoid valves, and high-pressure fluid fittings encountered in commercial and residential mechanical systems. Licensed plumbers, HVAC technicians, and industrial maintenance professionals typically install this size in threaded port seals, cap and plug assemblies, and face-seal fittings.

Key Features

• Fluoroelastomer (Viton) compound for high-temperature and chemical resistance up to 400 degrees F
• 75 Shore A durometer for low compression set and firm seal retention
• Suitable for petroleum product service including fuel and hydraulic fluids
• Low gas permeability makes it appropriate for vacuum service applications
• Round cross section, Dash 027 standard sizing for straightforward groove fitment
• Wide spectrum chemical compatibility reduces need for multiple compound inventories

Compatibility

Designed as a standard Dash 027 O-ring replacement compatible with petroleum products and systems requiring fluoroelastomer seals rated to 400 degrees F.

Installation Notes

Install by a qualified plumber, HVAC technician, or industrial mechanic following the system manufacturer's groove specifications for Dash 027 cross sections. De-energize, depressurize, and fully isolate the fluid system before removing the old seal. Lightly lubricate the O-ring with a compatible fluid or grease before seating to prevent roll and tearing during assembly. Do not use petroleum-incompatible lubricants on fluoroelastomer compounds.
