Center Pull Plugs

Center Pull-Tab plugs offer an easy and quick center pull-tab to remove the part. The tapered plug design allows these parts to plug multiple inner diameters. Two materials offered: PE for basic protection needs and TPR to protect threaded holes and is acid-resistant.

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.

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

High-Temperature Tapered Plugs

Our range of High Temperature Masking Plugs are available as a solid plug or with a hollow core. These reusable tapered plugs are available as either a premium Silicone Plug or as a cost-effective EPDM plug.

The Hollow Tapered Plugs provide an economical solution for large diameter holes. The hollow center aids compression for improved sealing.

Silicone Tapered Plugs are a premium option due to the high temperature rating of 600F (316C). High Temp Silicone Plugs can be used multiple times. Hardness; Durometer (Shore A) 55+5. Various colour options are available, including; Natural, Blue, Green, Grey, Pink, Purple, Red and Yellow.

The Black EPDM tapered plug is an economical material has a slightly reduced heat resistance with a high temperature rating of 435F (218C), but boasts superior chemical resistance.

  • Suitable applications include; Powder Coating, E-Coating, Plating and Anodizing.

Masking Pull Plugs

Masking Pull plugs are ideal for masking threaded and plain through-holes. To apply, just pull the thinner end of the plug through the hole until it stretches the larger end through the hole; then release it so it will compress and make a tight seal. Use the Flanged Pull plugs to mask the backside of the hole. These come in a premium high-temp silicone material or in an economical reduced temp EPDM material. Applications include Powder Coating, E-Coating, Plating and Anodizing.

Snap-Fit Plugs

Snap Plugs, also known as Snap Fit Connectors, are made from Low-Density Polyethylene (LDPE) with a vibrant red appearance.

The LDPE plugs benefit from a simple snap fitting design that once pushed into position, a single turn gives a tight fit. The range also features options with a pull-tab for quick removal.

Each snap fit plug covers a range of different thread sizes and styles, including; Standard/JIC, Metric and BSP.

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

Threaded O-ring Plugs - Metric Threads

Threaded O-ring Plugs for Metric Threads include a compressed flange lip and an O-ring to provide a watertight seal and superior leakage prevention for hydraulic threads. The threaded O-ring keeps contaminants like dirt, dust, debris, and moisture out of the hole.

It may be installed using a spanner, screwdriver, or by hand. Metric threads are available. The fine taper of metric tapered thread allows for the best possible force transmission. Used in oil and gas, plumbing, and automotive sectors where leak-proof seals are crucial to system integrity.

  • Material: HDPE, Nylon
  • Colour: Yellow, Orange

Threaded Protection Caps - Metric Threads

Threaded Protection Caps for Metric Threads threads and fittings protect threads and fittings from damage during production, storage, and shipment, ensuring that they remain in good condition and are ready for use when needed. The protection cap keeps contaminants like dirt, dust, debris, and moisture out of the hole.

Features a knurled head design that makes them easy to install and remove by hand by twisting them onto the pipe or tube. Suitable for Metric threads. Used in various applications, including hydraulic and pneumatic systems, automotive, and industrial applications.

  • Material: LDPE
  • Colour: Red

Threaded Protection Plugs - Metric Threads

Threaded Protection Plugs for Metric Threads protect threads and fittings from damage during production, storage, and shipment, ensuring they remain in good condition and ready for use when needed. The protection plug protects from contaminants like dirt, dust, debris, and moisture out of the hole.

Features a knurled head design that makes them easy to install and remove by hand by twisting them or onto the pipe or tube. Ideal for Metric thread applications exposed to high fluid flow residue and vibration. Used in various applications, including hydraulic, pneumatic and general engineering industries.

Threaded Sealing Caps - Metric Threads

These Threaded Sealing Caps for Metric Threads protect threads and fittings from damage during production, storage, and shipment, ensuring that they remain in good condition and ready for use when needed. The cap is fitted with an internal neoprene rubber sealing disk to limit fluid leakage, plus it reduces potential shearing. The protection plug protects from contaminants like dirt, dust, debris, and moisture from the hole.

It is easy to install and remove by hand, but its hex head allows the plug to be applied or removed with a spanner or socket at low torque. They are suitable to protect metric threads and are used in various applications, including hydraulic, pneumatic and general engineering industries.

  • Material: HDPE
  • Colour: Yellow

Threaded Sealing Plugs - Metric

These Threaded Sealing Plugs for Metric Threads are designed with a double sealing ring on the underside of the flange to provide a secure and reliable seal. The nylon material absorbs paint, minimising paint flaking and protects from contaminants like dirt, dust, and debris, not trapping liquid and moisture from the hole.

It is easy to install and remove by hand, but its hex head allows the plug to be applied or removed with a spanner, Allen key or socket. Due to its material, it is capable of withstanding temperatures in the range of -40F to 320F | -40C to 160C. They are suitable to protect metric threads and used in various applications, including hydraulic, pneumatic and general engineering industries.
