Value Collection ZMSCFS150 Fluorosilicone O-ring Dash 150

Product Description

The VALUE COLLECTION ZMSCFS150 is a Dash 150 fluorosilicone O-ring with a round cross section, designed for static and dynamic sealing applications in environments that demand resistance to fuels, oils, and wide temperature swings. It measures 2.862 inches inside diameter, 3.063 inches outside diameter, and 0.0937 inches thick. The fluorosilicone compound provides a Shore A hardness of 70 and maintains a reliable seal from -80 degrees F to 400 degrees F. This O-ring meets MIL-R-25988 Type 1 Class 1 requirements, making it a fit for aerospace, military, and industrial fluid-handling assemblies where material compliance is required.

This O-ring is used in applications involving fuel systems, hydraulic lines, and fluid transfer assemblies where standard silicone or nitrile compounds fall short. Its fluorosilicone formulation resists degradation from petroleum-based fuels, synthetic oils, and some solvents. Typical install scenarios include face seal fittings, boss-type ports, and flange joints in aerospace ground support, fuel-handling equipment, and industrial machinery. Plumbers, millwrights, and MRO technicians working on fuel or solvent lines will find this O-ring appropriate for those service environments.

Key Features

• Fluorosilicone compound resists fuels, oils, and solvents across a broad service range
• Operating temperature range of -80 degrees F to 400 degrees F
• Shore A hardness of 70 for a balance of pliability and compression resistance
• MIL-R-25988 Type 1 Class 1 compliant for military and aerospace use
• Round cross section for standard groove fitment in Dash 150 gland designs
• Sold individually — package quantity of 1

Compatibility

Designed to fit Dash 150 standard O-ring glands with a 2.862-inch inside diameter. Verify gland dimensions against the 2.862-inch ID, 3.063-inch OD, and 0.0937-inch cross-section thickness before installation.

Installation Notes

Shut down and depressurize the system fully before removing any existing O-ring or sealing component. Inspect the gland and mating surfaces for nicks, burrs, or contamination that could prevent a proper seal. Lubricate the O-ring lightly with a compatible fluid — confirm lubricant compatibility with fluorosilicone before use. Follow applicable industry standards such as AS568 for gland tolerances and torque procedures.
