Pipe Clamp Niczuk Obejma L-PST 11/2 (47-49) 1/2 — metal hose clamp for 47–49 mm pipes

Niczuk Obejma L-PST 11/2 (47-49) 1/2 is a metal hose clamp engineered to secure pipes and hoses with an outer diameter of approximately 47–49 mm. The clamp uses a screw-tightening mechanism that allows adjustable tension and reliable fixation. Constructed from corrosion-resistant materials, it is suitable for installations where a 1 1/2" size clamp is required and where a durable metal fastening is preferred.

Advantages

The screw-tightening design provides precise control over clamping pressure, enabling a snug fit around hoses and pipes. Metal construction improves mechanical strength and resistance to deformation compared with non-metallic alternatives. Corrosion-resistant finish extends service life in environments with occasional moisture exposure. The clamp’s adjustable range accommodates minor diameter variations within the 47–49 mm span, reducing the need to stock multiple fixed-size fasteners.

Suitable for

• Plumbing pipe connections with 47–49 mm outer diameter
• HVAC duct and hose fastening where a 1 1/2" clamp is specified
• Automotive and marine hose assemblies needing metal clamps
• General-purpose pipe installations and repair work

Key specifications

• Nominal size: 1 1/2" (suitable for pipes/hoses around 47–49 mm outer diameter)
• Type: Screw-tightening metal hose/pipe clamp
• Material: Metal with corrosion-resistant finish
• Adjustable range: approximately 47–49 mm outer diameter
• Fixation method: Mechanical screw for adjustable tension

How to use

Position the clamp around the hose or pipe so that the band fully encircles the fitting and the screw housing is accessible. Turn the screw clockwise using an appropriate screwdriver or hex driver to tighten the band until the clamp sits snugly without causing visible damage to the hose. If needed, loosen the screw counterclockwise to adjust position or remove the clamp. Ensure the clamp is tightened evenly and avoid over-tightening which can deform soft hoses or compress seals.

Usage recommendations

Use this metal hose clamp in applications where a secure, adjustable metal fastening is required. For continual exposure to aggressive chemicals or highly saline environments, consider verifying material compatibility and using dedicated corrosion-resistant grades or protective measures.
