What are Blanking Plugs?

Blanking plugs, the hidden gem in the family of precision engineering components, serve the critical function of sealing and protecting unused holes in machinery or structures. By efficiently blocking off these openings, blank-off plugs safeguard against the ingress of undesirable elements such as dust, moisture, and other contaminants, thereby enhancing the overall durability and performance of the system they are incorporated into.

How Blanking Plugs Work.

In essence, the operation of a blanking plug is straightforward but crucial. Depending on the type—be it pull tab, push fit, anti-vibration, or tapered—each is engineered to fit snugly into the designated hole, providing a secure and reliable seal. This acts as a physical barrier, making it particularly useful in applications that require dust or water-resistant conditions.

For instance, anti-vibration types are excellent for mitigating the effects of mechanical vibration, safeguarding the structural integrity of your engineering masterpiece.

What Material Plug Blanks are Made From.

At Accu, we understand the nuances that come with choosing the right material for your specific application. Our blank-off plugs are made from robust Low-Density Polyethylene and PVC. Low-Density Polyethylene offers excellent resistance to chemicals, while PVC stands out for its flexibility and durability. Given the precision requirements in engineering applications, the material you opt for can make a world of difference in performance and longevity.

What Size and Type Plugs Accu Offer.

Versatility is key in engineering solutions. Our range of blank-off plugs starts from those designed to fit a minuscule 1.6mm hole, scaling up to variants intended for a substantial 99.5mm hole. The blanking plug sizes are thus extensive, catering to a diverse array of needs. 


Moreover, we offer a variety of types such as pull tab for easy removal, push-fit for quick installation, anti-vibration for added stability, and tapered to suit a range of hole diameters. You might also find our blasting plugs and masking plugs to be valuable complements if you plan on adding a coating or finish to your workpiece.


Q: What is a blanking plug for?.

A: A blanking plug serves the purpose of sealing unused holes in machinery or structural components, thereby protecting them from dust, moisture, and other external elements that could compromise performance.

Q: How do you install a blanking plug?.

A: Installation depends on the type of blanking plug. Push-fit types can be installed by simply pushing them into the hole, while pull-tab types may require a tool for secure placement. Anti-vibration types usually come with threads that need to be screwed into place.

Q: How do you remove plastic blanking plugs?.

A: For pull tab types, you can easily remove the plug by pulling the tab. For push fit or anti-vibration types, you might need a tool like a flat-head screwdriver to carefully pry the plug out of the hole.

Q: Can I use PVC & rubber blanking plugs for outdoor applications?.

A: Yes, PVC & rubber blanking plugs offer excellent resistance to environmental factors and can be used in outdoor applications where flexibility and a tight seal are crucial.

Q: Are there hole blanking plugs suitable for high-vibration environments?.

A: Absolutely. Our anti-vibration blanking plugs are specifically designed to maintain their position and sealing capabilities in high-vibration settings, making them ideal for such demanding environments.
