Drain plug - BETRO-LOCK Standard

The core model of the BETRO‑LOCK series, designed for reliable and versatile sealing of drains in marine environments. Suitable as a drain lock, scupper plug and deck drain solution.

The BETRO‑LOCK Standard Sealing Plug is the backbone of the Betro‑Lock series. It features a T‑wrench made from acid‑proof steel with a through‑hole and a 3/8″R internal thread for mounting a pressure gauge, allowing monitoring of back pressure. This configuration applies to plug sizes 1 through 6.

Designed for versatility, the plug can introduce gas or liquid media inside the unit, making it suitable for use as an expanding drain plug. The top disk has a diameter larger than the rubber sleeve, providing impact protection against pipe ends. This makes it ideal for marine deck drains, scupper applications and other drain locking solutions in demanding marine environments.

Applications:

  • Sealing plug
  • Drain lock
  • Scupper plug
  • Drain cover
  • Expanding drain plug
  • Deck drain fitting
