Oetiker 18500057 2-ear Service Clamp Kit 124 Piece

Product Description

The OETIKER 18500057 is a 124-piece two-ear service clamp kit designed for securing hoses, tubing, and flexible connectors across a range of service diameters. The kit covers a clamping range from 5/16 inches to 1 inch, making it practical for a wide variety of plumbing, HVAC, and general mechanical service tasks. The 123 included clamps are zinc plated for corrosion resistance, and the kit ships with one zinc plated side jaw pincers tool for proper installation. The complete kit weighs 4 pounds. Plumbers, HVAC technicians, and mechanical service pros keep this kit on hand for quick, reliable hose clamp installations in the field.

This service clamp kit is suited for residential and light commercial service work involving hose and tubing connections. Two-ear clamps are commonly used where a tamper-resistant, low-profile connection is required, such as fuel lines, coolant hoses, drain connections, and other fluid-transfer applications. The included side jaw pincers are the correct installation tool for two-ear style clamps, allowing the technician to crimp the clamp ears securely without improvised tooling.

Installation Notes

Two-ear service clamps are installed by a licensed plumber, HVAC technician, or qualified mechanical technician using the included or compatible side jaw pincers. Shut off fluid flow and depressurize the line before removing or replacing any hose clamp. Position the clamp over the hose before sliding onto the fitting, then crimp both ears fully and evenly with the pincers to achieve a secure seal. Do not attempt to install two-ear clamps with general-purpose pliers, as improper crimping can result in clamp failure or hose damage.
