Flare Lapping Tool

  • VENDOR: Koul Tools
  • PART#: Surseat P-51
  • YOUR PRICE: Regular price $150.00


The Surseat flare lapping tool allows you to lap-in flared tubing to eliminate leaks in fuel and brake line joints. This innovative new tool removes irregularities in the flare and hones it to a perfect angle to enable the tube to seat with the fitting. The Surseat will not only perfect your newly-flared stainless steel, aluminum or copper lines, it can also repair the seal with the fitting of an existing brake or fuel line. It is based on the tried and true practice of lapping engine valves. A diamond dust coated lapping head with a precision 37° or 45° angle literally polishes the flare smooth to perfection. The Surseat is a valuable asset for car builders, automotive repair facilities, and hobbyists.
