Value Collection ZMSCFS152 Fluorosilicone O-ring Dash 152

Product Description

The VALUE COLLECTION ZMSCFS152 is a fluorosilicone O-ring with a round cross section, designed for static and dynamic sealing applications in environments exposed to petroleum fuels, oils, and wide temperature extremes. It measures 3.237 inches inside diameter and 3.438 inches outside diameter, with a wall thickness of 0.0937 inches. Rated for service from -80 degrees F to 400 degrees F, this O-ring carries a Shore A hardness of 70 and meets MIL-R-25988 TY 1 CL 1 compliance. It is identified by Dash Number 152 and is color-coded blue for material identification in the field.

This O-ring is used in aerospace, industrial, and commercial fuel system assemblies where resistance to petroleum-based oils, diester lubricants, and fuels is required. It is particularly suited for fuel system components and systems demanding reliable sealing at both low and high temperature extremes. The fluorosilicone compound provides performance in applications where standard silicone or nitrile compounds would fail due to fuel exposure or thermal cycling. Installation is typically performed by licensed mechanics, MRO technicians, or industrial maintenance professionals.

Compatibility

Compatible with petroleum products including petroleum oils and fuels, and diester base lubricants up to 350 degrees F. Designed for aerospace fuel systems and industrial assemblies requiring MIL-R-25988 TY 1 CL 1 compliant fluorosilicone seals. Note that fluorosilicone has limited strength and abrasion resistance; verify suitability for dynamic applications before installation.

Installation Notes

O-ring installation should be performed by qualified mechanics or maintenance technicians following applicable system service procedures. Depressurize and drain the system before removing or replacing seals. Inspect the groove and mating surfaces for burrs or contamination that could damage the O-ring during installation. Avoid twisting the O-ring during seating, and use only lubricants compatible with fluorosilicone compounds.
