A push-to-connect tubing fitting which has a body, a collett with tubing gripping teeth that engage the tubing, and sealing devices. The collett is disposed within a bore in the body of the fitting. The collett has tubing gripping teeth on its inner bore which mechanically engage the outer surface of the tubing. A first sealing device is positioned within an inner bore of the collett at a point closer to the tubing insertion opening of the collett than are the tubing gripping teeth. This first sealing device seals the tubing to the collett. A second sealing device is disposed between the collett and the body. This second sealing device seals the collett to the body of the fitting and effectively completes the seal between the tubing and the body.
