CL4S - Universal Supco Universal Hose Clamp 72, 4-5

CL4 - Supco Universal Hose Clamp 72, 4"–5"

The CL4 Universal Hose Clamp 72, 4"–5" is a genuine Supco replacement clamp designed for securing large-diameter hoses and flexible connections in appliance, HVAC, and general service applications. This stainless-steel screw-type hose clamp provides an adjustable 4" to 5" diameter range and is built for reliable fastening where a secure hose connection is required. Supco identifies the CL4 as a stainless-steel screw-type hose clamp with a 5/16" band and 1/4" screw head.

Supco CL4 is an aftermarket replacement component rather than an appliance manufacturer's OEM-specific part. Its universal design makes it useful for repair technicians, appliance installers, homeowners, landlords, and maintenance professionals who need a properly sized hose clamp.

Appliance Kingdom supplies appliance and HVAC-related replacement parts across Canada, with Canada-wide shipping and support to help customers select the correct component for their repair.

Function & Importance

A hose clamp provides mechanical pressure around a hose or flexible connection to help keep the hose securely attached to its fitting. The CL4 uses a screw-adjustment mechanism that allows the clamp to be tightened around connections within its specified 4" to 5" range.

Using the correct clamp size is important for maintaining a secure connection. A clamp that is too small may not fit around the hose, while an incorrectly sized or improperly tightened clamp may not provide the required holding force.

The CL4 features a stainless-steel construction, a 5/16" band width, a 1/4" screw head, and an SAE #06 standard designation.

Common Signs You May Need a Replacement Hose Clamp

A hose clamp may need replacement when the existing clamp:

• Is damaged, bent, or deformed
• No longer tightens securely
• Shows signs of corrosion or deterioration
• Cannot maintain a secure connection
• Has lost its ability to properly hold the hose in position
• Is missing during installation or repair
• Is being replaced as part of hose or connection maintenance

The CL4 is specifically sized for connections measuring 4" to 5" in diameter, so measuring the hose or connection before ordering is important.

Will Replacing the Hose Clamp Fix My Problem?

If a loose or damaged hose clamp is responsible for an unsecured hose connection, replacing it with a correctly sized clamp can restore the mechanical hold of the connection.

However, a hose clamp will not correct problems caused by a damaged hose, fitting, duct, or other component. Inspect the complete connection before installation and make sure the CL4's 4"–5" adjustment range is appropriate for your application.

Compatibility & Ordering Guidance

The CL4 is a universal hose clamp rather than a model-specific appliance component. It is intended for applications requiring a hose clamp within its specified size range.

Before ordering, verify:

• Required clamp diameter: 4" to 5"
• Hose or connection dimensions
• Available clearance around the connection
• Required clamp type
• Application requirements

Do not order based solely on the appearance of the existing clamp. Measuring the outside diameter of the hose or connection provides better fit confidence.

Installation Overview

Installation is generally straightforward when the clamp size and application are correctly identified.

Place the clamp around the hose or connection, ensure the hose is fully seated on its fitting, and tighten the screw mechanism until the clamp provides a secure hold. Avoid excessive tightening, which can damage the hose or deform the clamp.

For appliance, HVAC, plumbing, or other connected systems, follow the equipment manufacturer's service instructions and take appropriate safety precautions before beginning work.
