This three-handle installation tool is intended for use with stainless steel stepless ear clamps for cross-linked polyethylene (PEX) tubing and ASTM International F1807 or F2159 insert fittings (not included). The installation tool has a safety feature that releases the ratchet when the proper degree of clamp compression has been reached. The lightweight ratcheting pincer allows single-hand use, and this three-handle installation tool is suitable for use in plumbing applications such as installing home water lines.
