The o-ring is the one consumable in a Champion Quick-Lock joint. Everything else in the fitting is nickel-plated brass, stainless steel or technopolymer and does not wear. The o-ring is what actually seals against the outside diameter of the tube, and it is what you inspect every time a fitting comes apart.
Champion supplies them in packs of 12 in each tube size, in two compounds: standard temperature nitrile rated to 176 F, and high temperature Viton rated to 300 F.
Choose your compound and size from the dropdowns above.
Which Compound Do You Need?
| Compound | Max Temperature | Use It When |
|---|---|---|
| Nitrile, standard temp | 176 F | Normal shop air, nitrogen, vacuum and inert gas service. This is what ships in the fitting and what the vast majority of systems run. |
| Viton, high temp | 300 F | Runs close to a compressor discharge, an aftercooler or a heated dryer, hot plant environments, or where lubricant carryover and heat together are hard on nitrile. |
One caution worth stating plainly. The Viton o-ring is rated to 300 F, but the Quick-Lock system as a whole is rated to 176 F, because the tube, the paint and the other fitting components are. A high temperature o-ring buys you margin against a hot spot. It does not raise the rating of the pipe. If a run genuinely sees more than 176 F, the answer is to move the pipe further downstream of the heat source, or to use something other than aluminum pipe there. Call us and we will work out which.

Champion does not catalog a separate replacement o-ring for 14mm. The 14mm connection is a push-lock fitting that needs no torque, and its seal is supplied with the fitting.
Where the O-Ring Sits in the Joint
Champion's Quick-Lock fitting is six parts. Knowing which is which makes service obvious.
| Part | Material |
|---|---|
| Nut | Nickel-plated brass |
| Seal | High nitrile |
| Clamping washer | Stainless steel, Inox AISI 304 |
| O-ring seal | NBR as standard, Viton on the high temp part |
| Safety ring | Technopolymer |
| Body | Nickel-plated brass |
Ideal Applications
Routine service stock for any plant running Quick-Lock, re-sealing fittings that have been taken apart during a layout change, chasing a slow leak found on a commissioning test, and spares for a maintenance crib. A pack of twelve is cheap insurance against a Saturday morning with a leaking main and no parts.

Building a Complete Quick-Lock System
- Quick-Lock aluminum tubing, 14mm to 63mm
- Straight union connectors
- 90 and 45 degree elbows and street elbows
- Equal tees and reduction outlet tees
- Stem and reducing adapters
- Fitting plugs
Torque matters as much as the seal. Oil the tube lightly, push and rotate it fully home, then torque the compression nut to Champion's figure for that size: 26 in-lb on 20mm and 25mm, 35 in-lb on 32mm, 58 in-lb on 40mm, and 48 ft-lb on 50mm and 63mm. Heavy oil carryover combined with heat is what shortens standard nitrile life fastest, and the durable fix for that is proper coalescing filtration upstream rather than a shorter o-ring interval.
Ordering Notes

- Freight: freight collect from Huntersville, NC 28078 or Las Vegas, NV 89113.
- Photography: Champion publishes no product photograph for the o-ring packs, so this listing is deliberately shown without an image rather than with a stand-in.
- Shipping weights: Champion publishes no weight for these packs, so no catalog weight is carried on these variants.
