Value Collection ZMSCV3X30 Viton O-ring 30x36x3 Inch

Product Description

The VALUE COLLECTION ZMSCV3X30 is a Viton (fluoroelastomer) O-ring designed for static and dynamic sealing applications that demand resistance to elevated temperatures and aggressive fluids. It measures 30 inches inside diameter, 36 inches outside diameter, and 3 inches thick with a round cross section. The compound carries a Shore A hardness of 75, placing it in the hard range, which helps maintain seal integrity under compression. Rated for service from -15 degrees F to 400 degrees F, this O-ring is a dependable choice wherever thermal cycling and petroleum-based fluid exposure are primary concerns.

This O-ring is suited for industrial sealing applications involving petroleum products, hydraulic fluids, and chemical process media. Its large diameter makes it appropriate for flanged connections, large-bore cylinder heads, tank covers, and similar heavy-equipment joints in industrial and manufacturing environments. Licensed plumbers, pipefitters, and millwrights working on large-diameter fluid systems are the typical installers. The fluoroelastomer formulation also supports vacuum service and delivers low gas permeability, extending its usefulness to pneumatic and vacuum system applications.

Key Features

• Fluoroelastomer (Viton) material provides high temperature resistance up to 400 degrees F
• Rated to -15 degrees F for cold-temperature service
• Shore A hardness of 75 for reliable compression set resistance
• Round cross section for standard groove compatibility
• Good resistance to petroleum products and a wide spectrum of chemical media
• Low gas permeability suitable for vacuum service applications
• Black color; non-FDA-approved formulation

Compatibility

Designed as an OEM-style replacement or new-installation seal for large-diameter flanged and gasketed connections where fluoroelastomer O-rings with a 30-inch inside diameter are specified. Compatible with petroleum products and a wide range of chemical media per supplier documentation.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or millwright following applicable codes such as ASME or ANSI piping standards for the system being serviced. De-pressurize and drain the system fully before removing any existing seal or cover. Inspect the groove for scoring, corrosion, or debris before seating the O-ring; a damaged groove will compromise the seal regardless of O-ring condition. Do not use sharp tools to seat the ring, and avoid twisting or stretching beyond what is required for installation.
