Value Collection ZMSCV2.4X4.3 Viton O-ring 4.3in Id

Product Description

The VALUE COLLECTION ZMSCV2.4X4.3 is a Viton (fluoroelastomer) O-ring with a round cross section, measuring 4.3 inches inside diameter, 9.1 inches outside diameter, and 2.4 inches thick. Viton is a fluoroelastomer compound known for its resistance to petroleum products, high temperatures, and a wide range of industrial chemicals. This O-ring is rated for service from -15 degrees F to 400 degrees F and carries a hardness rating of 75 Shore A, placing it in the hard category. It is used as a static or dynamic sealing element in fluid and gas systems where standard rubber compounds would degrade. Maintenance technicians, plumbers, and industrial mechanics install this type of seal in pumps, valves, flanges, and hydraulic or pneumatic assemblies.

This O-ring is suited for applications involving petroleum-based fluids, hydraulic oils, fuels, and high-temperature service environments. Its low compression set and low gas permeability make it appropriate for vacuum service as well as pressurized systems. The large diameter and substantial cross-section thickness indicate use in industrial-scale equipment such as large pumps, compressors, process valves, or pipe flanges. It is sold in packages of 25 units, making it practical for facilities or service shops that perform frequent seal replacement on similar equipment.

Key Features

• Fluoroelastomer (Viton) construction provides resistance to petroleum products, fuels, and industrial chemicals
• Operating temperature range of -15 degrees F to 400 degrees F
• 75 Shore A hardness for a firm, durable seal under compression
• Round cross section for consistent seating in standard O-ring grooves
• Low compression set and low gas permeability support vacuum and pressurized service
• Package quantity of 25 units suits shop stock and repeat-service applications

Compatibility

Designed as a replacement or maintenance seal for industrial pumps, valves, compressors, flanges, and hydraulic or pneumatic assemblies requiring a fluoroelastomer O-ring with a 4.3 inch inside diameter and 2.4 inch cross-section thickness. Compatible with petroleum products and systems requiring broad chemical compatibility.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician following the equipment manufacturer's service procedures. De-energize the system and relieve all pressure and fluid before removing the old seal. Inspect the O-ring groove for damage, burrs, or contamination before seating the new ring. Avoid twisting or overstretching the O-ring during installation; use an appropriate lubricant compatible with fluoroelastomer compounds and the system fluid.
