APEX Tank wall feed-through ATF-20, Kerbl

The APEX ATF-20 tank wall fitting by Kerbl is a specialized installation component designed to create leak-proof hydraulic connections in water tanks and animal watering systems. The product solves the problem of leaks and unstable pipe connections where water installations pass through tank walls, ensuring a durable and pressure-resistant threaded outlet.

Application

The fitting is used in demanding agricultural and technical installations:

• Livestock watering systems: installation of float valves (including high-capacity APEX valves) in troughs and tank drinkers.
• Liquid storage systems: creating connections in rainwater and technical water tanks on farms.
• Industrial and workshop applications: building liquid dosing systems requiring pipe transitions through polyethylene or metal walls.
• Working environment: indoor and outdoor installations exposed to water and changing temperatures.

Principle of operation

The device works using a mechanical compression sealing system. The fitting consists of a threaded body, locking nut, and sealing gaskets. After inserting the body through the tank wall opening, tightening the nut evenly compresses the seals against the wall surface, creating a watertight barrier even on slightly uneven surfaces. The ATF-20 internal thread allows direct installation of valves or hydraulic fittings.

In practice

• High sealing performance → specially selected gaskets prevent water leaks, protecting buildings and reducing water loss.
• Corrosion resistance → technical plastic construction ensures long service life in humid and aggressive agricultural environments.
• Easy installation → standard thread and durable locking nut enable quick assembly using basic plumbing tools.
• Expert Kerbl quality → designed as a system component fully compatible with APEX series valves, minimizing installation errors.
