Rubber plugs

Our long-term partnership with PLUGTITE – manufacturer of the next generation of service and maintenance plugs – allows us to deliver the safest plugging solutions.

Proud partner of PLUGTITE


PLUGTITE developed three models to meet different requirements of all industries: Plugtite™ Industrial, Plugtite™ Heat Resistant and Plugtite™ Hygiene. They channeled their decades-long experience into creating their own compounds and blends. PLUGTITE’s expertise in rubber plugs is truly outstanding. We can only recommend their products that are made of compressed rubber to create a tight fit. The plug preserves its shape under extreme circumstances without deterioration. The material itself if extremely durable, it doesn’t crack, shrink or discolor, even when exposed to sunlight. They are very easy to use; inserting and releasing is done by a simple squeeze and press. All plugs come in three sizes: small (2mm-14mm), medium (5mm-24mm) and large (15mm-45mm).

The major function of rubber plugs is to protect important machine parts from contamination when they are transported or impacted by different weather conditions. Mechanical items are also often closed with rubber plugs during powder-coating process.

Commonly used technology in the following industries

Product ranges

Plugtite™ Industrial

This model was developed specifically for industrial applications. The industrial rubber plugs can be used during maintenance or storage of machinery. The compressed rubber creates a perfect sealing for fluids such as hydraulics and chemicals, preventing any leakage. The material does not react with chemicals frequently used for industrial applications, which combined with the perfect sealing, decreases the chance of contamination significantly. Moreover, it is made of an extremely durable rubber that doesn’t crack under extreme conditionsThey can be used from -25°C up to 90°C, leaving a wide enough window to perform maintenance work on machinery.

Plugtite™ Heat Resistant

Plugtite™ Heat Resistant is designed to resist high temperatures up to 230°C (445°F). General applications include electrostatic lines, die casting etc. Due to the more extreme environment, the oil and chemical resistance of the heat resistant plugs is also greater than that of other plugs. They provide the perfect, leakage-free sealing at high temperatures, without splitting or deteriorating.
