Value Collection ZMSCV1.6X4.1 Viton O-ring 4.1 in Id

Product Description

The VALUE COLLECTION ZMSCV1.6X4.1 is a heavy-duty Viton (fluoroelastomer) O-ring designed for static and dynamic sealing applications across industrial, fluid handling, and mechanical systems. It measures 4.1 inches inside diameter with a 1.6 inch cross section, producing an outside diameter of approximately 7.3 inches. The round cross section profile seats consistently in standard O-ring grooves. Viton compound provides high resistance to heat, petroleum products, and a wide range of chemicals, making it a reliable choice where standard rubber compounds fail. Hardness is rated at 75 Shore A, classifying it as a hard durometer ring suitable for higher-pressure and high-temperature service environments.

This O-ring is appropriate for use in pump housings, valve bodies, hydraulic fittings, and similar assemblies where petroleum-based fluids, fuels, or elevated temperatures are present. The large cross section and inside diameter suit industrial-scale equipment rather than residential plumbing. It is a practical fit for maintenance and repair operations in refineries, manufacturing facilities, heavy equipment, and chemical processing where Viton seals are specified. Plumbers, millwrights, and industrial maintenance technicians commonly install this size. The package quantity is 25 pieces per order with a minimum order quantity of one package.

Key Features

• Fluoroelastomer (Viton) compound resists petroleum products, fuels, and a broad spectrum of chemicals
• Operating temperature range of -15 degrees F to 400 degrees F suits high-heat applications
• 75 Shore A hardness provides a firm, low-compression-set seal under sustained load
• Low gas permeability makes it suitable for vacuum service
• Round cross section seats in standard O-ring grooves without special tooling
• Sold in packs of 25, allowing stocking of common service sizes

Compatibility

Designed as a standard round-cross-section Viton O-ring replacement for industrial sealing applications requiring a 4.1 inch inside diameter and 1.6 inch cross section in systems handling petroleum products or operating at elevated temperatures. Not FDA approved; not intended for food-contact or pharmaceutical sealing service.

Installation Notes

Relieve all system pressure and depressurize fluid lines before removing the existing seal. Clean the O-ring groove thoroughly and inspect for scoring or corrosion before installing the replacement. Apply a compatible lubricant to the O-ring prior to seating to reduce installation stress and prevent tearing. Confirm groove dimensions match the O-ring cross section before final assembly to avoid extrusion or under-compression failures.
