Hose Clamps

Hose clamps secure hose connections around fittings and coupling shanks in commercial plumbing, construction, agriculture, industrial maintenance, irrigation, municipal work, and quarry or mining applications. This category includes adjustable worm gear, micro worm gear, T-bolt, constant-tension, heavy-duty, and preformed clamp styles, along with a center punch tool for compatible clamp bands.

Hose Clamp Buying Guide

Start with the outside diameter of the assembled hose connection, then select a clamp whose listed range includes that measurement. From there, compare the adjustment method, construction, band width where stated, and installation approach required for the connection.

Use Cases

Secure hose connections across commercial work

Represented clamp options support construction, agricultural, industrial, commercial plumbing, maintenance, irrigation, municipal, quarry, and mining hose-connection work.

How to Choose

Match the listed clamping range

Compare the hose outside diameter with the clamp’s stated range. Available examples span from 5/16 to 5/8 inch for a micro worm gear clamp through 3-5/8 to 5-1/2 inches for a worm gear clamp.

Applications

Choose a design for the connection

Worm gear clamps offer adjustable sizing; T-bolt clamps are designed to apply sealing pressure around a coupling shank; constant-tension clamps address hose expansion and contraction caused by temperature changes.

Additional Information

Review installation and order details

Some clamps use hex-head screws, while the preformed clamp has a lever-operated lock. Center-punch clamps with 5/8-inch bands use a compatible center punch tool, and listed minimum order quantities vary by item.

5/16–5/8 in.Smallest listed range

The represented micro worm gear clamp fits within this range.

3-5/8–5-1/2 in.Largest listed range

A represented worm gear clamp covers this range.

5/8 in.Center-punch band compatibility

The center punch tool supports clamps used with 5/8-inch bands.

4 or 10Listed multi-unit minimums

The constant-tension clamp has a minimum order of 4; one heavy-duty clamp has a minimum order of 10.

T-bolt and constant-tensionT-bolt models have fully threaded T-bolts, high-torque designs, and nylon locking nuts; constant-tension design responds to temperature-related hose movement.Consider T-bolt styles for coupling-shank connections and constant tension where temperature changes or non-uniform hose surfaces can affect the seal.
Heavy-duty and preformedHeavy-duty options have three spot welds and 360-degree bridge sealing surfaces; the preformed clamp uses a lever-operated lock and smooth inside diameter.Compare the required diameter range, material, installation method, and whether a reusable design or lever-operated lock is needed.
Planning Guide

Plan the right fit before choosing

1. Measure and match

Select a clamp range that fits the hose connection

Use the hose outside diameter at the connection as the starting point. Select a listed range that includes the required diameter rather than choosing only by clamp style.

  • Micro worm gear option: 5/16 to 5/8 inch.
  • Worm gear examples: 1-1/8 to 3 inches, 1-9/16 to 2-1/2 inches, and 3-5/8 to 5-1/2 inches.
  • T-bolt examples: 2-3/16 to 2-1/2 inches, 2-5/16 to 2-5/8 inches, and 2-7/8 to 3-3/16 inches.
  • Heavy-duty examples: 2.2 to 2.32 inches and 3.39 to 3.58 inches.
2. Compare clamp mechanisms

Match adjustment and sealing needs to the clamp type

The represented products use several clamping approaches. Compare the mechanism with the installation and connection requirements of the job.

  • Worm gear and micro worm gear designs adjust around compatible hose connections.
  • Fully threaded T-bolts allow adjustment for sizing and tension; listed T-bolt clamps also include nylon locking nuts.
  • The constant-tension design responds to hose expansion and contraction from changing temperatures.
  • The heavy-duty style uses a 360-degree bridge sealing surface for even pressure, while the preformed style uses a lever-operated lock.
3. Confirm construction, bands, and installation

Check the details that affect compatibility

Review the stated material, band width, and installation method for each item. Stainless steel construction is represented across several clamp types, while the preformed clamp is carbon steel.

  • Listed band widths include 3/8 inch on the preformed clamp and 9/16 inch on selected worm gear and constant-tension clamps.
  • Selected worm gear, micro worm gear, and constant-tension clamps have hex-head adjustment points.
  • The center punch tool is for 5/8-inch clamp bands and uses ratchet-action tensioning before locking by striking the punch with a mallet or hammer.
  • Heavy-duty clamps are reusable and use metric bolt and thread designs that require no special installation tools.
FAQ

Common questions before buying

How do I choose a hose clamp size?

Measure the hose outside diameter at the connection and choose a clamp with a listed range that includes that measurement.

What is the difference between worm gear and T-bolt hose clamps?

Worm gear clamps use an adjustable worm gear design. Listed T-bolt clamps use fully threaded T-bolts and are designed to apply sealing pressure around a coupling shank.

When is a constant-tension hose clamp useful?

A constant-tension clamp is designed for connections where temperature changes or non-uniform hose surfaces can affect the seal, because it responds to hose expansion and contraction.

What tool is used with 5/8-inch center-punch clamp bands?

The represented center punch tool supports 5/8-inch clamp bands, tensions the clamp with ratchet action, and locks it by striking the tool punch with a mallet or hammer.
