Value Collection ZMSCVB75240 Viton O-ring Dash 240 5-pack

Product Description

The VALUE COLLECTION ZMSCVB75240 is a Dash 240 Viton (fluoroelastomer) O-ring packaged in a quantity of 5. It measures 3.75 inches inside diameter, 4 inches outside diameter, and 0.125 inches thick with a round cross-section. The compound carries a Shore A hardness of 75, placing it in the hard durometer range. Viton fluoroelastomer provides strong resistance to petroleum-based fluids, high temperatures up to 400 degrees F, and a wide range of chemicals. Low compression set and low gas permeability make this O-ring a reliable choice in static and dynamic sealing applications where hydrocarbon exposure or elevated temperatures are a concern.

This O-ring is suited for use in HVAC refrigerant systems, hydraulic assemblies, fuel handling equipment, compressor fittings, and industrial process lines where petroleum products, oils, or high-temperature gases are present. Plumbers, HVAC technicians, and industrial maintenance professionals commonly use Dash 240 O-rings as face-seal or port-seal replacements in standard AN and SAE port configurations. The -15 to 400 degrees F operating range covers most residential and light commercial mechanical system environments as well as many demanding industrial service conditions.

Key Features

• Fluoroelastomer (Viton) material provides broad chemical compatibility and high-temperature performance
• Operating temperature range of -15 degrees F to 400 degrees F
• Shore A hardness of 75 for reliable sealing under compression
• Low compression set helps maintain a consistent seal over extended service cycles
• Low gas permeability makes this O-ring suitable for vacuum and gas-containment service
• Sold in a pack of 5 to support multiple repairs or installations from a single order

Compatibility

Compatible with petroleum products, oils, and a wide spectrum of chemical media. Designed as a standard Dash 240 O-ring replacement in any application requiring an AN or SAE Dash 240 fluoroelastomer seal.

Installation Notes

Installation should be performed by a qualified technician familiar with the sealing system being serviced. Always depressurize and isolate the system before removing the old O-ring, and clean the mating groove thoroughly to remove debris or residual sealant. Avoid rolling or twisting the O-ring during installation, and apply a compatible lubricant to reduce the risk of nicking the material. Follow applicable system-specific codes and manufacturer service procedures when returning the assembly to service.
