Profec W4 Stainless Steel 304 Worm Drive Hose Clip – 140–160 mm Clamping Range, 12 mm Band
This heavy-duty worm drive hose clip from Profec is manufactured entirely from stainless steel 304 (1.4301) in accordance with W4 classification, meaning every component — band, housing, and screw — is stainless steel. The 12 mm wide band provides a broad, even clamping force across the hose surface, minimising the risk of cuts or deformation on flexible hose walls. The adjustable clamping range of 140 mm to 160 mm makes it suitable for large-diameter hoses commonly encountered in pool pipework, irrigation main lines, and greenhouse water supply systems.
The perforated band design, visible in the product image, engages precisely with the worm screw thread to allow fine incremental adjustment and reliable re-tightening over the service life of the installation. The 0.8 mm band thickness delivers the rigidity needed to maintain consistent sealing pressure under vibration and thermal cycling without permanent deformation. The hex-head screw accepts a standard 7 mm socket or flat-blade screwdriver, speeding up installation in confined spaces.
Specifications
- Type: W4 (all-stainless construction)
- Clamping range: 140 mm – 160 mm
- Band width: 12 mm
- Band thickness: 0.8 mm
- Band material: Stainless steel 304 (1.4301)
- Housing material: Stainless steel 304 (1.4301)

Compatibility
Suitable for securing flexible hoses with an outer diameter between 140 mm and 160 mm. Typical applications include large-bore pool return hoses, irrigation trunk-line connections, pump suction hoses, and greenhouse supply manifolds. The all-stainless W4 construction is appropriate for outdoor, humid, and mildly corrosive environments where zinc-plated or W1/W2 clips would be unsuitable. Not recommended as a structural fitting or for applications requiring a certified pressure-rated connection.

In details
- All-stainless W4 construction — band, housing, and screw in SS304 — resists corrosion in wet outdoor environments
- 12 mm wide band distributes clamping load evenly, reducing hose deformation
- 140–160 mm range covers large-diameter pool and irrigation hoses in a single clip
- 0.8 mm band thickness maintains grip under vibration and thermal cycling
- Standard hex-head screw accepts 7 mm socket for fast installation in tight spaces
- Single-use tightening direction only — over-tightening beyond 160 mm is not possible; correct size selection is critical
- SS304 offers good but not maximum corrosion resistance — SS316 clips should be considered for salt water or chlorinated immersion
- No integrated seal; a separate sealing sleeve or hose tail barb is required to achieve a leak-free joint
