Squeeze together and insert half into one side of tubing, splice will spring back when released and stay in place securely to connect two pieces of tubing from inside. Leaving an unnoticeable seam. Fits inside of 2" O.D. tubing, intended for tubing with .065 wall, when connecting tubing of different wall thicknesses or when used with tubing on a slope. Special ordered for 2" OD tubing upon request. Spices could be made of either brass or stainless steel, pending on availability at time of shipment.
Fittings with inserts are made to fit with .050" wall tubing. They do not fit with pipes. When you purchase flush fittings without tubing, please measure your tubing for OUTSIDE diameter and wall thickness to ensure material will fit together.
