Mechanical seals are a trusted way to seal conduits while accommodating either cables or pipes that need to pass through while staying protected from intrusions like water, pests and gas. Custom mechanical seals can be manufactured to create a seal that can be designed to meet your unique sealing needs.

Compared to other types of seals, like spray foam, mechanical seals offer an extremely long-lasting and hardy solution. Polywater | Hauff-Technik’s mechanical seals are made of durable materials that won’t corrode when installed in harsh environments. Custom mechanical seals are available to fit any size of conduit to ensure total watertight and gastight performance. 

This answer will depend on the environment in which the mechanical seal is installed, but Polywater | Hauff-Technik’s mechanical seals have a 10-year warranty. 

Stick lubricant is recommended while installing mechanical seals. This helps facilitate faster movement of the rubber when the seal is tightened to a specific torque. 

This depends on your project and application. The right mechanical seal offers a durable, complete seal that protects cables or pipes from damage. It’s important to prioritize quality construction, corrosion resistance, and even certifications, if possible. For example, Polywater | Hauff-Technik offers custom mechanical seals that are certified by UL and CSA and considered watertight for sealing conduit, tubing, and raceways entering a structure or building.

Modular link seals, like the PGKD, are most commonly used for sealing annular spaces within the electrical, gas, water and HVAC markets.
