Pin hole pipe leak repair clamps


Pin-hole leak repair clamp utilizes a locator pin which guides a pointed cone seal into the leaking hole.

Pressure is then applied to the cone seal by a force screw and once the seal is compressed the pin may be removed thus completing the seal.


Pin hole clamp repair leaks are capable of withstanding working pressures of up to 138 bar (2000 psi).
