Spliced & Vulcanized O-Rings: Custom Solutions for Unique Applications

Our spliced and vulcanized O-Rings are ideal when standard O-Rings don't meet your needs or when you need a faster solution than what molded O-Rings can provide. At The O-Ring Store LLC, we expertly craft O-Rings from extruded O-Ring cord, vulcanizing them to achieve the size (ID) you require. We offer seamless spliced Standard Inch and Metric O-Rings in all standard materials, across various cross sections, as well as convenient Splicing Kits. Each O-Ring <48" undergoes rigorous inspection with the Olypsys® Large Format Grid measuring system to guarantee maximum accuracy.

Current Lead Times: Dependent on cord stock availability.

• Up to 24 O-Rings: Typically ~2-5 days. 
• 25-100 O-Rings: Typically ~5-10 days.
• 100+ O-Rings: Typically ~10-15 days.

This process supports custom sizes that differ from standard molded O-Rings, ensuring you receive a perfectly tailored solution.

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

Viton (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.
