Midland Industries CC-3740 2-ear Circle Clamp 1-1/2 in

Product Description

The MIDLAND INDUSTRIES CC-3740 is a 2-ear circle clamp designed for securing hose, tubing, and flexible conduit connections in plumbing, HVAC, and light industrial applications. Constructed from carbon steel with a white zinc-plated finish for corrosion resistance, this clamp features a 1-1/2 inch nominal size with a minimum clamp diameter of 1.457 inches and a maximum clamp diameter of 1.575 inches. The two-ear design allows the clamp to be crimped with standard ear clamp pliers, creating a permanent, vibration-resistant connection. At 0.034 pounds, it is a lightweight but durable fastening solution suited for professional installation in tight spaces.

This clamp is commonly used in residential and light commercial settings where a reliable, low-profile hose or tubing connection is required. Typical applications include PEX tubing connections, automotive heater hose, HVAC flex duct collars, pool and spa plumbing lines, and other systems requiring a secure, tamper-resistant clamp. The 1-1/2 inch nominal sizing fits a range of standard hose and tube outside diameters within the 1.457 inch to 1.575 inch clamp diameter range. Plumbers, HVAC technicians, and pool service professionals commonly install this type of clamp during new installation or repair work.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or pool service professionals using dedicated ear clamp crimping pliers - do not substitute with standard slip-joint or tongue-and-groove pliers, as improper crimping will compromise the seal. Shut off the water supply or air pressure to the system before installing or replacing clamps on active lines. Once crimped, the 2-ear clamp is a permanent fastener and cannot be reopened without cutting; ensure correct tubing positioning before crimping. Follow applicable IPC or local plumbing codes for clamp type and spacing requirements.
