How does a worm gear clamp work?
Screw/band (worm gear) clamps When the screw is turned, it acts as a worm drive pulling the threads of the band, causing the band to tighten around the hose (or when screwed the opposite direction, to loosen). Screw clamps are normally used for hoses 1/2 inch diameter and up, with other clamps used for smaller hoses.
Are worm gear clamps reusable?
They are also referred to as Band Clamps, however band clamps can also be strap clamps. Stainless Steel Worm Gear Clamps have a zinc coating (galvanized) for increased resistance to corrosion. Worm gear clamps are easy to use, remove and are completely reusable.
How much pressure can a worm gear hose clamp hold?
The flexible air hose, rated at 200 psi (1,379 kilopascals or 13.79 bar) was attached to a hard line using a brass coupling and an HS10 Dixon worm gear clamp rated for used up to 30 psi (207 kilopascals or 2.07 bar).
What are the different types of hose clamps?
There are four overarching categories of hose clamp; screw/band, spring, wire and ear. Each different hose clamp is used depending on the type of hose in question and the attachment at the end. As one of the most regularly used hose accessories, questions surrounding the use of hose clamps are frequent and plentiful.
Can you open a worm gear clamp?
Open the worm gear hose clamp by turning the head of the worm gear screw counterclockwise. Use the screwdriver or a 5/16-inch nut driver until the worm gear screw threads are free from the slotted band.
How do you use a worm clamp?
How to Use Hose Clamps
- Expand the hose clamp by turning the screw counterclockwise. Make it large enough to slide over the hose.
- Slide the hose clamp over the hose.
- Slide the hose over the fitting that you want it to attach to.
- Slide the hose clamp over the joint between the fitting and the hose.
How do you measure worm gear clamps?
To determine the size needed, install the hose on the fitting or pipe (which expands the hose), measure the outside diameter of the hose, then select a clamp that accommodates that diameter in about the middle of its range.
How tight should a hose clamp be?
The proper torque for screw type hose clamps is to tighten them until the rubber outer shell protrudes through the screw slot just enough to be even with the outside of the clamp. Any further is considered too tight and can cut into the hose, actually causing the hose to be loose after several heat cycles.
Are hose clamps OSHA approved?
OSHA Construction standard 1926.302(b)(5) states that “The manufacturer’s safe operating pressure for hoses, pipes, valves, filters, and other fittings shall not be exceeded”. A water hose clamp can also cut into compressed air hose material easily and cause it to break.
Is a worm clamp adjustable?
Clamps are made of high-quality metal for a long lifespan. This set contains 100 adjustable steel clamps. Clamps can be used for hoses from 8-44mm in size.
What do the clamps on a worm drive do?
Clamps come packed in a box with individual compartments for each clamp size. To make sure they won’t cut into hose and tube, they have a smooth band with rolled edges. An extended tail acts as a liner to protect soft hose and tube from being cut by the slots in the band.

How big do worm drive hose clamps need to be?
An extended tail acts as a liner to protect soft hose and tube from being cut by the slots in the band. Create 4″ diameter and larger worm-drive clamps that withstand high-temperature applications. Create 2″ diameter and larger smooth-band worm-drive clamps.
What kind of clamps do you use for pneumatic hoses?
Worm Gear Clamps. Use durable worm gear clamps from Grainger to help secure many types of hoses, including pneumatic and exhaust hoses. A general-purpose worm gear hose clamp is interlocked to prevent shearing, while clamps used for exhaust have no holes, helping them prevent marring of the hose and fumes escaping.
