Heavy-Duty Hose Clamps

Hose clips and clamps are devices used to attach and secure a hose onto a fitting, such as a barb or nipple. They are typically made from metal, such as stainless steel or galvanized steel, and are designed to tightly grip the hose and fitting in order to prevent the hose from slipping off or leaking. Hose clips and clamps are used in a wide range of applications, including automotive, industrial, and domestic settings.

There are several different types of hose clips and clamps available, each with its own unique characteristics and uses. For example, worm drive hose clips are commonly used in automotive and industrial applications because they are easy to install and provide a strong, secure connection. These clips feature a screw-like design that tightens around the hose and fitting as the screw is turned, creating a tight seal. Another popular type of hose clip is the T-bolt clamp, which uses a bolt and nut system to clamp the hose onto a fitting. T-bolt clamps are often used in high-pressure applications because they can provide a very strong and secure connection.

In terms of technical characteristics, hose clips and clamps are typically rated for use at specific pressure and temperature ranges. For example, a hose clip may be rated for use at pressures up to 100 pounds per square inch (PSI) and temperatures up to 300 degrees Fahrenheit. It is important to choose the right type of hose clip or clamp for the specific application in order to ensure that the connection is secure and able to withstand the expected operating conditions.

What makes a T-bolt clamp heavy duty?
The construction. A solid bolt and trunnion pull a wide, smooth-inner band evenly around the whole joint, rather than a screw engaging slots in a perforated band at one point. That gives far higher and more even clamping force, and it holds tension through heat cycling where a worm drive creeps loose.

When do I need one?
On boost, intercooler and turbo pipework, on any joint that sees pressure pulses, and anywhere with heavy vibration - engine mounts, plant, marine. Also on soft silicone in larger bores, where a perforated worm drive band can bite into the hose. For coolant and low-pressure air, a worm drive is fine.

What sizes do you stock?
23 adjustment ranges from 17mm to 19mm up to 122mm to 130mm, with 18-24mm band widths and M5, M6 or M8 heads depending on size, in W1 zinc plated and W4 stainless. Available singly, in 10 and 100 packs, and in assorted boxes from 46 up to 210 clamps.

How do I size one?
Size to the outside diameter of the hose once fitted over the pipe, not to the bore, and aim for the middle of the clamp's adjustment range rather than either extreme. A clamp at the end of its travel either will not close or has very little thread engaged, which is where failures start.

W1 or W4?
W4 stainless for engine bays, outdoors, marine and anywhere exposed to coolant or salt. W1 zinc plated is cheaper and suits dry indoor use. On a boost joint you may need to remove and refit several times during a build, and a corroded clamp that will not undo is a genuinely miserable job.

How tight should it be?
Firm and even - compress the hose against the pipe without crushing it. T-bolts can generate a lot of force, so it is easy to over-tighten and damage a silicone hose. Re-check after the first few heat cycles: the joint beds in and the clamp usually needs a small nip afterwards.
