BS 5315 British Standard Worm Drive Hose Clamps

Our BS 5315 Series Hose Clamps represent the benchmark for quality in the British market. Designed with a pressed thread and rounded band edges, these clips provide a consistent 360-degree seal while protecting the hose surface. Whether you are dealing with aggressive fluids in a chemical plant or high-vibration environments in a vehicle engine, RockClamp's BS 5315 clips offer the reliability required by the most demanding engineering standards.

This standard establishes critical dimensions, material specifications, performance criteria, and test methods to ensure the quality, reliability, and interchangeability of these clamps within the UK and international markets.

W4 stainless steel non-perforated band worm drive hose clamp is one type of BS 5315 hose clamps. The material is all parts stainless steel 301/304

Features of BS 5315

The standard covers several essential aspects to guarantee clamp performance:

Materials (Mild Steel, 304/316 Stainless Steel):

Bands: Must be made from corrosion-resistant material, typically stainless steel (such as grades similar to 304 or 316) or carbon steel with a protective coating (e.g., zinc plating).

Housings and Screws: Must be similarly corrosion-resistant. For worm-drive clamps, the screw and housing are often made from plated carbon steel or stainless steel to match the band.

Design and Dimensions:

The standard provides precise dimensional tolerances for the band width, thickness, and the range of adjustment.

It defines the design of the housing and the engagement mechanism (e.g., the worm gear must engage smoothly with the band's perforations or slots).

Performance and Testing:

Pressure Resistance: The high torque Clamp must be tested to ensure they can retain a seal without failure or excessive deformation at a specified proof pressure.

Tensile Strength: The band and the housing must withstand a minimum tensile load without breaking or pulling apart.

Corrosion Resistance: Materials and finishes must demonstrate adequate resistance to corrosion, often verified through salt spray testing.

Common Applications

BS 5315 clamps (worm drive hose clip) are found in a wide range of industries requiring reliable hose connections. Ideal for automotive, industrial, and agricultural applications where a high-strength, leak-proof seal is required, including:

• Automotive: Engine cooling systems, fuel lines, and turbocharger connections.

• Industrial: Hydraulic systems, pneumatic lines, and general machinery.

• Marine & Offshore: Corrosion-resistant fastening for saltwater environments (W4/W5 Grade).

• Agriculture: Irrigation systems and farm machinery maintenance.
