Koul Touls SurSeat Line Lapper

Simple in design and effective in function, the Surseat Line Lapper utilizes a diamond dust lapping head to gently lap in a flared tubing end to create a better seal. The Surseat will smooth out those irritating irregularities after flaring the tube that cause you to spend even more time on your project than you anticipated. KOULtools owner Dick Raczuk envisioned the Surseat Line Lapper as a logical solution to leaky fittings based on the practice of lapping engine valves. "People have been lapping engine valves for 100 years. Why??? So they don't leak! When you flare a tube, you should lap it in as well so it doesn't leak."

The Surseat P-51 will work with flared tubing from 3/16” to 1/2” in diameter.

From Koul Tools
Since the invention of stainless braided rubber hose, racers and mechanics have been fighting the problem of installing it into the socket part of the assembly. If your lucky and get a clean cut on the end of that hose, you might get it in. Most of the time a little fuzz appears on the hose end and the battle begins. It is not only time consuming, it can get bloody. KOUL tools has delivered a solution that makes the assembly a snap. Manufactured of a high tech composite, it is virtually indestructible. No need to worry about vise marks or wearing out. Just insert the socket into the tool, twist the hose in, and in less than 10 seconds you have it assembled. You can repeat this several times without recutting the hose end. The tool can pay for itself the first time you don't have to scrap some hose because it got too short trying to clean up the end. You'll be amazed at the amount of time you'll save. After using this tool, you will say to yourself, "KOUL".
