Hole plugs are used for pipe end protection, and thread protection and have many other benefits.

Plastic Hole Plug Applications & Uses

  • Used for blanking holes
  • Finishing purposes - such as tube ends
  • Used for sealing
  • Protection - they create a tight seal to remove potential threats such as ingress.
  • Able to withstand elevated temperatures

Parallel Protection Plugs

Parallel Protection plugs for masking are made from a TPE material that is highly resistant to shredding and ideal for threaded applications. Also, this material has a good resistance to acids often used to remove rust from metal before any type of painting or powder coating operation is performed.

Push-In Barrel plugs are general-purpose plugs built to cover and close a hole. These can be applied or removed quickly and have convexed sides designed to ensure a secure fit.

Push-In Plugs for NPT Threads

A plug specially designed for the plugging of NPT tapered threaded fittings.

The tapered design means the product is able to plug multiple inside diameters - making it highly versatile. In order to assure a proper fit; the plug dimension should be approximately one percent larger than the inside diameter of the part (minimum of 0.020 inches).

  • Material: Low-Density Polyethylene (LDPE)
  • Colors: Blue, Yellow, Black and Red

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).

Tapered Caps & Plugs - Wide Flange

Wide Flange Tapered Caps & Plugs provides a greater protection to threaded and non-threaded pipes, ports, and access points during storage and transit against damage, dirt, moisture, debris, and corrosion. Designed to allow the part to plug multiple inside diameters or outside diameters.

Easy to install and remove due to their threaded and smooth connectors. Wider flange provides greater support for bearing surfaces and prevents the plug from being accidentally pushed down through the contact piece. Suitable for use in hydraulic systems, automotive components, chemical or medical industries.

  • Material: LDPE
  • Colour: Blue, Red, Yellow
