offers the best designed tools for stopping flow in 1/2 In. up to 8 In. PE pipe. Different models handle a wide range of pipe sizes and applications. Sliding bar handles make work in tight places easier and increase leverage for tightening. Fine-pitched thread on feed screw allows for a controlled, low-effort squeeze. Grease fittings at friction points make operation smoother and extend tool life. Aluminum bars are anodized or painted for protection from the elements. All PE squeeze-off tools use positive stops to prevent damage caused by over-clamping. Multiple size/SDR settings on one pair of stops provide quick, convenient over-squeeze protection for standard pipe sizes. Note: strongly recommends use of the PEX grounding accessory (#4619) with PE squeeze-off tools. Use a grounding accessory as a precaution against static build-up. Dissipate the charge and minimize the possibility of ignition.
