Top Tier FKM Viton O Rings In Rich Brown, 388 90D Spec, Built Tough To Handle Blistering Heat And Diesel Fuel Without Cracking, Heavy Duty Industrial Seal Pack Worth Grabbing
✔️ 19 Inch ID X 19-3/8 Inch OD X 3/16 Inch CS Seal Pack
Viton fluoroelastomer seals deliver steady sealing performance in hydraulic pumps, engine manifolds, and industrial fluid transfer lines. These rich brown rubber rings hold firm compression under intense pressure cycles while blocking aggressive chemicals from causing leaks.
✅ 90 durometer fluorocarbon compound handles rapid thermal swings from minus 20 to plus 400 degrees Fahrenheit✅ Low volume swell of just 1 percent after prolonged diesel fuel contact at standard operating temperature
✅ Meets strict AMS 7259 aerospace standards with steady 8 percent compression set for reliable leak control
✅ Repels mineral oils, brake fluids, solvents, and ozone without hardening or losing structural strength
💡 What makes FKM fluoroelastomer seals more handy than standard nitrile rings in high heat setups?
These advanced polymer compounds maintain consistent sealing force when temperatures spike far beyond typical rubber limits.
- High fluorine content blocks chemical breakdown against fuels, acids, and hydraulic fluids.
- Steady elastomeric memory prevents material hardening and keeps mating surfaces tightly compressed.
- Superior aging resistance dramatically reduces replacement frequency and minimizes costly downtime.
