Plastic 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 clamp adjustable?
A worm drive clip tightens by a screw engaging slots in the band, so it covers a range of diameters rather than one fixed size - for example 9mm to 12mm. That means one clip suits a spread of hose sizes, and it can be loosened and refitted repeatedly, which a crimped or spring clip cannot.

What sizes do you stock?
18 adjustment ranges from 9mm to 12mm right up to 135mm to 165mm, built to DIN 3017 with a 12mm band, 0.8mm thick and a 7mm hex head, in W1 zinc plated and W4 stainless. Available in 10 packs, 100 packs and assorted boxes.

How do I pick the right range?
Size to the outside diameter of the hose once fitted over the pipe, not the bore, and aim for the middle of the clip's range. A clip at the very end of its travel either will not close far enough or has almost no thread engaged, which is where the failures happen.

How tight should it be?
Firm, not crushed. Compress the hose evenly against the pipe without the band biting in - over-tightening causes more leaks than under-tightening does. Re-check after the first few heat cycles, because a new joint beds in and a clip that felt tight when cold often needs a small nip.

Where should the clip sit?
Squarely over the section of hose supported by the pipe stub underneath, never overhanging the hose end and never on the curve of an elbow. If the pipe has a bead or barb, position the clip so the hose is pulled down behind it - that is what stops a joint blowing off under pressure.

When should I use something else?
On boost, intercooler and turbo pipework, use a T-bolt clamp. A worm drive concentrates its force near the screw housing and its perforated band can bite into soft silicone, and it creeps loose under heat cycling. On small-bore fuel and vacuum lines, use mini clips instead.
