Value Collection ZMSCFS145 Fluorosilicone O-ring Dash 145

Product Description

The VALUE COLLECTION ZMSCFS145 is a fluorosilicone O-ring with a round cross section, designed for static and dynamic sealing applications that demand wide temperature resistance and chemical compatibility. It measures 2.55 inches inside diameter and 2.75 inches outside diameter, with a 0.0937-inch thickness. Fluorosilicone compound delivers reliable sealing performance in fuel, oil, and solvent environments while maintaining flexibility across an extreme temperature range. Licensed plumbers, hydraulic technicians, and industrial maintenance mechanics install this O-ring in fluid and pneumatic systems where standard silicone or nitrile compounds fall short.

This O-ring is suited for aerospace, automotive fuel systems, and industrial fluid-handling assemblies where both low-temperature flexibility and high-temperature stability are required. It conforms to MIL-R-25988 TY 1 CL 1, making it appropriate for military-specification applications. The Dash 145 designation follows AS568 standard sizing, allowing straightforward identification and replacement in groove-dimensioned assemblies. It is sold individually and is appropriate for single-unit service replacement or prototype work.

Key Features

• Fluorosilicone compound resists fuel, oil, and many solvents while maintaining elasticity
• Rated from -80 degrees F to 400 degrees F, covering wide temperature extremes
• MIL-R-25988 TY 1 CL 1 compliant for mil-spec and demanding industrial applications
• Dash 145 AS568 standard sizing for consistent groove compatibility
• Shore 70 hardness provides firm sealing force with adequate flexibility
• Round cross section for use in standard O-ring grooves

Compatibility

Designed as a standard AS568 Dash 145 O-ring replacement for static and dynamic seal grooves in fluid-handling, pneumatic, and fuel system assemblies requiring fluorosilicone material and MIL-R-25988 TY 1 CL 1 compliance.

Installation Notes

Depressurize and drain the system fully before removing the existing O-ring. Clean the groove and mating surfaces to remove debris, old sealant, or residual fluid that could prevent a proper seal. Lubricate the O-ring with a compatible grease before installation to reduce the risk of nicking or rolling during assembly. Avoid using petroleum-based lubricants if the service fluid is incompatible with mineral oil.
