Value Collection ZMSCV3X27 Viton O-ring 27mm Id 33mm Od

Product Description

The VALUE COLLECTION ZMSCV3X27 is a Viton fluoroelastomer O-ring designed for static and dynamic sealing applications across HVAC, plumbing, hydraulic, and industrial fluid systems. It measures 27 mm inside diameter, 33 mm outside diameter, and 3 mm thick with a round cross section. The material is fluoroelastomer, rated hard at 75 Shore A hardness, with a working temperature range of -15 degrees F to 400 degrees F. Its low compression set and low gas permeability make it a reliable choice for high-temperature and vacuum service environments. Technicians and mechanics reach for this ring when standard nitrile or EPDM seals fall short of chemical or thermal demands.

This O-ring is suited for residential and commercial applications where exposure to petroleum-based fluids, fuels, oils, or hydraulic media requires a chemically resistant seal. Common install scenarios include fuel system fittings, refrigerant-side service ports, hydraulic cylinder assemblies, pump housings, and valve bonnets. It is sold in a package of 10 pieces, making it practical to keep on hand for repeat service calls. Its broad chemical compatibility makes it a go-to replacement seal across a wide range of fluid handling equipment.

Key Features

• Fluoroelastomer (Viton) material provides wide-spectrum chemical compatibility including resistance to petroleum products
• Working temperature range of -15 degrees F to 400 degrees F suits high-heat service environments
• 75 Shore A hardness with a hard hardness rating for controlled compression under load
• Low compression set maintains sealing force over repeated thermal cycling
• Low gas permeability makes this ring suitable for vacuum service applications
• Round cross section for standard O-ring groove fitment
• Sold in a package of 10 pieces to support ongoing service inventory

Compatibility

Designed for use with petroleum products and compatible fluid media in systems requiring fluoroelastomer sealing. Consult groove dimensions to confirm fit before installation.

Installation Notes

Installation should be performed by a qualified technician familiar with sealing system design and applicable codes. De-pressurize and drain the system fully before removing any existing seals or fittings. Lightly lubricate the O-ring with a compatible fluid or grease before seating it in the groove to reduce the risk of twisting or tearing during assembly. Do not over-stretch the ring during installation, as fluoroelastomer material can be damaged by excessive elongation.
