Overview

DEL fitting seals are designed to eliminate leakage due to scratches on the sealing surface, improper torquing, or poor finishes on tube ends, in high or low pressure applications. For use with AN, MS, and JIC 37° flared fittings, DEL fitting seals also reduce tube flare cracking by reducing torque needed, eliminating nose damage to the fitting, and allow reuse of hardware. Approved by NASA, SAE, Air Force, Army, Navy, and major aerospace contractors.

Del Fitting Seal 1/2 OD Aluminum

Fitting seal - great if you need it. First be sure there is enough slack in the tubing to fully tighten the nut. Second these are very fragile. Suggest that you place the seal on a b-nut cap until the last 1/2 inch to where it is installed. Get the flair out of the way so you can install the seal without interference. install seal and tighten b nut. Works great.

Best way I have found to seal steel on steel fittings. Also helpful when there is a minor leak without over torque.
