Discover more about the Worm Drive Hose Clamps range.

Worm drive hose clamps are precision-engineered assembly hardware designed to secure hoses over fittings, preventing leakage in both non-pressurised and lightly pressurised systems.

Commonly used in plumbing, automotive, industrial, commercial and food-grade applications, these types of hose clamps are tightened over a hose utilising a worm gear mechanism, providing consistent and adjustable clamping force. For instance, in an automotive cooling system, a worm hose clamp ensures the radiator hose remains sealed to the fittings, even under thermal expansion.

How Worm Gear Hose Clamps Work

Worm gear hose clamps operate via a threaded screw, or "worm", housed within the clamp’s band. As the screw turns, it engages with the perforated band, drawing it tighter around the hose. This controlled tightening allows for a secure fit without damaging the hose, making them suitable for both rigid and flexible connections. Their ease of use and reusability also make them a preferred choice for maintenance and assembly applications.

Materials Worm Drive Hose Clamps Are Made From

At Accu, we have a variety of stainless steel worm gear hose clamps to choose from. To begin with, stainless steel A2 offers excellent corrosion resistance, making it ideal for most indoor and outdoor applications. For marine and food processing environments, our stainless steel A4 variants provide superior resistance to chlorides and corrosive environments.

Size and Types of Worm Screw Hose Clamps Available

Our worm screw hose clamps are available in diameters ranging from 8mm to 520mm, accommodating a wide variety of hose sizes and system requirements. If you need a clamp with additional clamping power for high-pressure hosing, take a look at our t-bolt clamps, which may be more suitable.

FAQs

Q: What is the alternative to a worm gear hose clamp?

A: Alternatives include plastic hose clamps, o-clips or ear clamps and t-bolt clamps, depending on pressure requirements and hose material.

Q: How tight should worm clamps be?

A: Worm clamps should be tightened until the hose is secure without deforming or damaging it. Over-tightening can compromise the hose structure, while under-tightening can allow the hose to still fall off the fittings.

Q: Are worm drive clamps good?

A: Yes, worm drive hose clips offer reliable, adjustable clamping for low to medium pressure applications and are known for their ease of installation and durability.

Q: Why is it called a worm clamp?

A: The name comes from the screw mechanism, which resembles a worm gear that engages with the band to tighten the clamp.
