SPECIAL O-RINGS
We stock a full line of o-rings in a wide variety of sizes, shapes, and compounds. Popular offerings include: Viton® O-Rings, Buna-N O-Rings, Silicone O-Rings, Chemraz® O-Rings, EPDM O-Rings, PTFE O-Rings, Neoprene O-Rings, Metric O-Rings, Back-Up Rings, X-Rings, Square Rings, Spliced O-Rings. We also make custom o-rings for specific applications.
MIL-SPEC O-RINGS
Compounds are approved to nearly every military, aerospace, ASTM, SAE, automotive, petroleum industry and commercial specification. The most commonly used specifications are the AMS, AS, AN, M, MS, MIL, and NAS specifications.
Specifications indicated by asterisk (*) require that the o-ring manufacturer be on The Qualified Products List (QPL).
BACKUP RINGS
Backup rings are designed to prevent extrusion in rubber o-ring sealing systems. There are three basic types of PTFE back-up rings in use: single turn (scarf cut), multi-turn (spiral cut), and solid (uncut) configurations. Our backup rings are made from either one of two materials, PTFE or rubber. Rubber backup rings are called contoured backup rings. The material of choice for rubber contoured rings is 90 durometer nitrile.
PHARMACEUTICAL O-RINGS
Pharmaceutical o-rings are used in pharmaceutical, biotec, food & beverage applications. Seal & Design has many compounds available that meet FDA, USP Class VI, 3-A or NSF 61 specifications.
VITON O-RINGS
Viton® (fluorocarbon rubber) has excellent resistance to high temperatures, ozone, oxygen, mineral oil, synthetic hydraulic fluids, fuels, aromatics and many organic solvents and chemicals making it a good choice for an o-ring material.
X-RINGS
X-Rings, provide greater sealing efficiency and lower friction than a traditional O-ring. The multi-lobe (Quad) design resists rolling in dynamic application preventing spiral failure. The multi sealing points also reduce the amount of force needed to seal and extends the life of the seal.
X-Ring Advantages
- Deeper o-ring groove means lower diametrical squeeze, which means dynamic sealing can be acheieved with less friction
- Greater sealing capacity but with a groove for lubrication, aiding dynamic sealing applications
- Greater stability for dynamic applications. The x-ring resists roll much better than an o-ring
- More resistant to spiral failure
