Closing Plugs

Closure plugs are designed to ensure the secure sealing of threaded holes in hydraulic tanks and systems, protecting them from dust, dirt, and external agents. Made from Polyamide 6-66 reinforced with glass fiber, these plugs provide excellent mechanical and chemical resistance, maintaining their properties even at extreme temperatures (-30°C to +100°C). The gasket, made of NBR or other materials, ensures a perfect seal, preventing fluid leaks.

Closure plugs are available in a wide variety of models to suit different applications, such as the TCN/OR with an integrated O-ring or the TCA with a level rod for more precise fluid control.

Description

Closing plugs are designed to securely seal threaded holes, protecting them from external contaminants such as dust, dirt, and liquids. The use of materials like Polyamide 6-66 reinforced with 30% glass fiber provides the plugs with exceptional resistance to impacts, extreme temperatures, and mechanical deformations.

Main models

The closing plugs offered on our website are available in a wide variety of models to suit different industrial applications. Among the main models are:

  • TCN/OR: plug with hexagonal head and integrated O-ring seal, ideal for ensuring a hermetic closure with moderate tightening torque.
  • TCA: plug with a galvanized steel level rod, designed to monitor the oil level inside tanks or systems, with min-max level markings available on request.
  • TCNS/TSN: plugs equipped with a vent hole for proper system ventilation, available in various configurations and with the option of an NBR gasket for enhanced sealing.

One of the key features of these plugs is their ability to operate within a wide temperature range, from -30°C to +100°C, with peak temperatures up to 120°C for some specific models such as the TCNB, which is reinforced with 50% glass fiber. This thermal resistance makes them ideal for environments where high heat and pressure are constant.
Another important feature of these plugs is the sealing gasket, which can be made from different materials depending on the application requirements. The standard gasket is made of NBR, a material known for its excellent resistance to oils and hydraulic fluids, but other options are available upon request to meet specific operating conditions.

Closing plugs also play an essential role in maintenance operations, allowing quick removal and reinstallation without compromising the system’s seal or protection. Models such as TM even integrate a magnet to collect metal particles, ensuring optimal lubrication and extending machinery lifespan.
