Fluorine Rubber O-Rings 15mm OD 9mm ID 3mm

These metric FKM O-rings measure 15mm outer diameter, 9mm inner diameter and 3mm cross-section. They suit automotive, hydraulic and plumbing repairs where reliable sealing is required. The pack contains five brown rings ready for immediate installation. They serve technicians and DIY owners who need chemical-resistant gaskets for pumps, hoses and filters.

Upgrade from standard rubber seals

Standard rubber degrades quickly when exposed to fuels, oils or temperatures outside a narrow band. These FKM rings withstand a range from -30°C to 280°C and resist mineral oils, greases, aliphatic, aromatic and chlorinated hydrocarbons plus many organic solvents. The jump is worth it whenever the joint sees aggressive media or sustained heat that would cause ordinary elastomers to harden, swell or crack. They also tolerate a working pressure of .3 bar without extrusion.

Fit into a build with 9mm bores

The 9mm inner diameter matches common metric ports on pressure washers, water hoses and plumbing pipework. No special tools are needed beyond a clean groove and light lubrication during assembly. Because the material resists a broad chemical spectrum, one ring type can replace several specialised seals, reducing the number of spare-part lines a workshop must stock. Confirm the exact groove dimensions before ordering to ensure proper compression.

Questions about this item

What groove dimensions suit the 15 mm outer diameter and 3 mm cross-section?

The rings have a 15 mm outer diameter and 3 mm cross-section; machine the groove to match those dimensions for a proper seal.

How do I install the O-ring without stretching it past its 70A durometer limit?

Lubricate the ring with a compatible fluid, then press it evenly into the groove using a blunt tool so the 70A hardness material seats without over-stretching.

When should I replace the rings given the -30 °C to 280 °C temperature range?

Inspect for hardening, cracking or permanent deformation after prolonged exposure near the 280 °C upper limit; replace at the first sign of deterioration.
