The W4 British-Type Non-Perforated Band Hose Clamp is a robust and reliable clamping solution that shares the superior core design of its German counterpart (like the W5) but is typically manufactured to different regional specifications and often at a more cost-effective price point. It is a heavy-duty clamp designed for applications where a standard perforated clamp is insufficient. Our customers buy hose clamps from us, they are happy to our quality and price.

Material:

W4 - All parts stainless steel 301/304

Our Product Range for Sale

• Worm Drive Clamps (British/American/German Type): Versatile and high-torque for general piping.

• T-Bolt Heavy Duty Clamps: Best for high-pressure suction and discharge hoses.

• Double Wire & Spring Clamps: Ideal for corrugated hoses and cooling systems.

• Custom Solutions: Need a specific size or material (W1, W2, W4, W5)? We offer full OEM/ODM services.

Features:

Non-Perforated (Solid) Band:

Like the German-type, the defining feature is its smooth, solid stainless steel band with no perforations. This eliminates weak points, significantly increasing the band's tensile strength and resistance to shearing under pressure, vibration, and overtightening.

Rolled Band Edges:

The edges of the band are smoothly rolled over. This prevents the sharp edges from cutting into or damaging the hose during tightening, which is crucial for protecting expensive or soft hoses like silicone.

Worm Drive Mechanism:

The screw engages with continuous, precision-rolled threads on the inner surface of the band. This provides a smooth and secure tightening action with a very high torque capability. The housing is typically a heavier, more substantial casting or stamping compared to standard clamps.

Material: Typically 304 Stainless Steel (A2 Grade):

While specifications can vary, the W4 is most commonly manufactured from AISI 304 (A2) stainless steel. This offers excellent general corrosion resistance for most environments, including:

 - Automotive and marine engines

 - Industrial machinery

 - Agricultural equipment

 - General plumbing and piping

Many of our customers buy hose clamps 316 stainless steel for more corrosive environments, we also produce 316 stainless steel hose clamps
