12" to 18" ID X 0.118" (3.00mm) C/S Vulcanized Fluorocarbon FKM O-Rings 75 Durometer

300mm ID to 450mm ID / 12" to 18" ID

Spliced & Vulcanized O-Rings - Current typical lead time is 5-10 days for up to 10 O-Rings. More than 10 pieces may take 10-15 days depending on cord stock.  

Spliced and vulcanized o-rings are a great solution when standard o-rings cannot be used or cannot be purchased quickly. Spliced o-rings are made from extruded o-ring cord and then vulcanized to form the o-ring size (ID) required. The O-ring Store provides seamless spliced Standard Inch & Metric O-rings in all of the standard materials in a variety of cross sections, as well as Splicing Kits.

This process allows for custom sizes larger and different than standard molded o-rings.

Chemical Resistant and High Heat Fluorocarbon FKM O-Rings 75 Durometer

Fluorocarbon FKM, has excellent resistance to high temperatures, ozone, oxygen, mineral oil, synthetic hydraulic fluids, fuels, aromatics and many organic solvents and chemicals. Fluorocarbon FKM has a temperature range of -20F to +400F, and provides excellent resistance to a wide variety of chemicals, weather and compression set requirements. The relatively high level of fluorine in Fluorocarbon FKM materials allows for exceptional resistance to chemical attack, but with limited low temperature capabilities.
