Smith+Clamp (Plidco Products)

About This Project


About this product


♦ The PLIDCO® Smith+Clamp™ is light-weight and easy to handle which makes using it to shut-off high pressure pit-hole leaks simple and sensible. The exclusive pilot pin makes it possible to locate pit-hole leaks even if they can’t be seen which makes the Smith+Clamp™ the product you want to use in dark spaces or on submerged lines. The force screw exerts pressure directly on the sealing cone, rather than applying force with the draw bolts, which reduces the danger of caving in corroded pipe. This product can be used while the pipeline is in service.

♦ The maximum allowable working (maop) pressure of a PLIDCO® Smith+Clamp™ is based on a 1/8” diameter pit-hole. Larger holes, up to ½” diameter, can be sealed at reduced pressures. Contact PLIDCO® for pressure recommendations.

♦Available in standard sizes 0.5” through 48”; 2000 maop. Custom sizes available upon request.

♦ Buna-N is standard packing for the cone. Viton, Silicone and other packing options are available upon request.
