Plastic Metric Threads

 (8 product groups)


Hexagonal Caps

Our range of Hexagonal Caps have a rigid design that allows for easy fitting and removal. Available in all common hydraulic coupling sizes.

The caps have a hexagonal shape, which makes them ideal for the protection of hexagonal connections and assemblies. However, the caps versatility means they are also suitable for the protection of round components. This makes them a flexible and economical choice for a range of projects.

  • Material: Polyethylene (PE)
  • Color: Natural

Flanged Caps

Flanged caps are designed to protect threaded connectors or fittings but are used to fit both threaded or round surfaces. You can assemble or remove these caps by hand or automated equipment.

Soft Knurled Caps

Soft Knurled Caps are a simple and economical way of protecting metric and UNF threads during painting, assembly or transportation. They have a knurled exterior and are manufacured from a soft, durable TPE that provides a better grip and a tight fit. Protects pipe ends from damage, and keeps dirt and debris out.

Easy to install and remove. They can operate in a temperature from -60 C up to 135 C.

Commonly used in plumbing, HVAC, and industrial applications.

  • Simple and economical way of protecting metric and UNF threads.
  • Easy to install and remove.
  • Operatures in temperatures from mimimum -60 C up to maximum 135 C.
Material: TPE Color: Blue Series Code: SRF0010

Tear-Tab Caps

Tear Tab Caps are a standard, off-the-shelf solution that will allow you to meet your customers demands without those all-too-common time delays.

Tear Tab Caps are quick-fit and quick-release caps. As a rapid solution, they can be easily fitted and removed across an array of applications, including: critical hydraulic tubes and pipes, such as those that carry oils and other fluids around vehicles and machineries. This makes them an ideal choice for the specialist vehicle manufacturing industry, and other automotive and manufacturing sectors.

Tear Tab Caps also assist in the protection of tube and pipe ends during transportation and storage. They protect parts from damage, dirt, moisture and other forms of ingress. These caps are highly versatile, and ideal for a range of applications and different threads, including; BSP, GAS, UNF, JIC and NPT.

Made from Low Density Polyethylene (LDPE), the caps feature a simple tear-away tab for quick release and fast removal. The ease of extracting the Tear Tab Cap from the hydraulic pipework makes the removal process faster. By simply pulling the tab, the cap splits open, tearing away.

The LDPE material is tough and flexible. They provide many of the advantages of PVC caps, such as integrity and cleanliness.

  • Colours: Blue, Natural and Yellow
  • RoHS Compliant

Push Fit End Caps

Push Fit End Caps are a simple and economical way of protecting metric and UNF threads during painting, assembly, and transportation.

Manufactured from a soft, durable TPE that provides a better grip, and a tight fit. Easy to install and remove.

Commonly used in plumbing, HVAC, and industrial applications.

  • Suitable metric and UNF threads.
  • Protects pipe ends from damage. Keeps dirt and debris out.
  • Can operate in temperatures ranging from -60 C up to 135 C.
Material: TPE, , LDPE Color: Blue, , Red Series Code: SRCFBTPE, SRCFB

Tapered Caps & Plugs - Standard

Tapered Caps and Plugs made from Red and Blue Low Density Polyethylene (LDPE). A versatile assembly that can be used as both a tapered cap or a tapered plug.

The tapered design allows the part to plug multiple inner diameters or cap multiple outside diameters. The Tapered Cap Plug protects the assembly against damage, dirt, moisture and corrosion during storage and shipping. The series has parts with a heavy duty design, which includes a rugged wall and seal rings for maximum protection.

To assure a proper fit;

  • The tapered plugs outer diameter should be approximately 1% larger than the inner diameter of the part (minimum of 0.020 inch).
  • The tapered caps inner diameter should be approximately 1% smaller than the outside diameter of the part (minimum of 0.020 inch).

Threaded Protection Plugs

Threaded Protection Plugs designed for use on Metric, BSP and Gas Threads. Safeguards threads and fittings from damage and contaminants during production, storage and shipment. The knurled head design allows easy hand installation and removal on pipes and tubes, by simply twisting.

  • Features a knurled head design that makes them easy to install and remove by hand by twisting them onto the pipe or tube.
  • The protection plug protects from contaminants like dirt, dust, debris, and moisture out of the hole.
  • Used in various applications, including hydraulic, pneumatic and general engineering industries.
Material: LDPE Color: Red Series Code: SR1002,

Threaded Plugs with Gasket

Threaded Plugs with Gaskets are intended to establish a tight and secure seal that prevents dust, dirt, or other undesired components from entering. The inclusion of a gasket (washer) seal improves sealing capabilities, adding an extra layer of protection against leaks and impurities.

Threaded Plugs are easy to install and remove from the application using a straight screwdriver, hex key or wrench. They can withstand temperatures from -30C up to +90C.

Frequently used in hydraulic and pneumatic systems, automotive, and general engineering sectors.

  • Provides a tight seal, preventing contaminants from entering.
  • Easy to install and remove using a straight screwdriver, hex key or wrench.
  • Can withstand temperatures from -30C up to +90C.
