Value Collection ZMSCA80135 Aflas O-ring Dash 135

Product Description

The VALUE COLLECTION ZMSCA80135 is an Aflas O-ring designed for reliable static and dynamic sealing in demanding chemical, refrigeration, and fluid-handling applications. With a 1.925-inch inside diameter, 2.13-inch outside diameter, and a 0.103-inch cross-sectional thickness, this Dash 135 ring seats precisely in standard Dash 135 grooves. The 80-durometer hardness rating places it in the hard range, giving it strong resistance to extrusion under pressure. The Aflas compound delivers broad chemical compatibility and handles a working temperature range of 25 degrees F to 450 degrees F, making it suitable for high-temperature sealing environments where standard nitrile or EPDM compounds fall short.

This O-ring is used in industrial fluid systems, refrigeration circuits, chemical processing equipment, and hydraulic assemblies. Its Aflas compound makes it a common choice when the sealed media includes acetic acid, animal oils, bases, brake fluids, fuels, hydraulic oil, or refrigeration fluids such as Freon-type refrigerants. It is typically installed by HVAC technicians, plumbers, pipefitters, and industrial maintenance mechanics working on systems where aggressive media or elevated temperatures rule out standard elastomers. Sold in a package of five rings.

Key Features

• Aflas compound provides moderate resistance to petroleum products and excellent resistance to ozone and weathering
• Good compression set retention for long-term sealing performance
• Excellent compatibility with refrigeration fluids including Freon-type refrigerants
• 80-durometer hardness reduces extrusion risk in pressurized applications
• Wide working temperature range: 25 degrees F to 450 degrees F
• Standard Dash 135 designation for direct groove fitment with no modifications

Compatibility

Compatible sealed media include acetic acid, animal oils, bases, brake fluids, fuels, hydraulic oil, and refrigeration fluids. Designed as an OEM-style replacement O-ring for any system using a standard Dash 135 groove specification.

Installation Notes

Shut down and depressurize the system fully before replacing any O-ring seal. Inspect the groove for scoring, corrosion, or debris and clean it before seating the new ring. Lightly lubricate the O-ring with a compatible lubricant to aid installation and prevent pinching or twisting. Follow applicable system service codes and manufacturer torque requirements for any fittings or caps that retain the seal.
