SHARKS plastic trumpet shears SHK 376

Product detailed description

Plastic pipe cutting is a routine task in plumbing and heating installations, particularly in residential and commercial buildings where non-armoured plastic piping systems are used. Installers frequently encounter the need to cut pipes accurately and cleanly, especially during the layout of water supply lines, drainage systems, or underfloor heating circuits. The SHARKS SHK 376 plastic pipe cutters are specifically designed for this purpose, ensuring clean, burr-free cuts with minimal physical effort. The tool is suitable for use in confined spaces and on-site, where precision and ergonomics are essential for long working hours.

When working with plastic piping systems, it is important to use the correct cutting tools to avoid deformation or damage to the pipe. The SHK 376 is optimised for smooth-walled plastic pipes without reinforcement, such as those used in standard water supply applications. The tool's design allows for controlled, repeatable cuts, reducing the risk of misalignment or uneven edges that could compromise the integrity of the joint.

Technical parameters

Installation and connection

Before cutting, ensure the pipe is securely supported to prevent bending or twisting during the operation. Position the cutters around the pipe, aligning the blades with the intended cut line. Apply even pressure and rotate the handles until the cut is complete. The SHK 376 requires minimal force due to its optimised blade geometry and mechanical advantage. After cutting, inspect the end for burrs or deformations that could interfere with fitting installation.

Compatibility and accessories

The SHK 376 is compatible with all standard non-armoured plastic pipes within its specified diameter range. It is often used in conjunction with sealing tapes or thread sealants such as LOCTITE 55 - 160 m, which are applied to threaded connections to ensure leak-free joints. For sealing flat surfaces or pipe ends, a sealing ring may also be required. Installers should ensure that the correct cutting tool is used for the specific pipe material to avoid blade wear or damage to the pipe.

Technical background for designers

The SHK 376 operates on a scissor-action principle, where two blades are brought together to cut through the pipe wall. The blades are made from special tool steel, ensuring long service life and consistent cutting performance. The ergonomic handle design and mechanical advantage of the tool reduce the force required for cutting, making it suitable for use in tight or awkward positions. The tool is designed for integration into standard plumbing workflows, where clean, accurate cuts are essential for proper joint formation and system integrity. The choice of tool should consider the pipe material and wall thickness to ensure compatibility and avoid premature blade wear.

Service and operation

Regular inspection of the cutting blades is recommended to ensure they remain sharp and free from damage. If the blades become dull or chipped, they should be replaced with genuine SHARKS replacement blades to maintain cutting efficiency. The tool should be stored in a dry location to prevent corrosion. No scheduled service intervals are specified, but routine checks during tool use are advisable to ensure continued performance. If the tool shows signs of wear or malfunction, it should be withdrawn from service until repairs or replacements are made.

Frequently asked questions

Can SHARKS SHK 376 cut reinforced plastic pipes?
No, the SHK 376 is designed for smooth-walled plastic pipes without reinforcement. Reinforced or armoured pipes require a different cutting method or tool.

What is the maximum pipe diameter that SHK 376 can cut?
The SHK 376 is suitable for cutting plastic pipes with diameters up to 42 mm. Beyond this size, a different tool is required.

Can the blades be replaced?
Yes, the blades are replaceable and made from special tool steel. Replacement ensures continued cutting performance and tool longevity.

Is the tool suitable for use in tight spaces?
Yes, the compact design and light weight of the SHK 376 make it suitable for use in confined or awkward working positions.
