Fitting Structure

  • The inner surface of Whitemarine pipes and fittings is completely smooth with no restriction whatsoever.
  • The very low roughness prevents build-up of dirt or deposits, which allows for limited pressure drops.
  • Soaks up vibrations while sailing.
  • Maximum sealing for both gravity and vacuum systems.

Collari antisfilamento

Anti-slip Collars

The standard range includes anti-slip collars to ensure clamping between pipe and fitting.

First, the collar grips the pipe or fitting where it is installed to prevent it from slipping off. And second, because of its special shape it wraps around the end of the socket, pipe, or fitting, while still allowing it to move to compensate for any thermal expansion. Typical applications for this collar are:

  • Internal pipe overpressure.
  • Negative or positive pressure systems.
  • Tight space installations.
  • Locking of plugs on the push-fit sockets, in order to carry out future system inspections.
