Custom block and manifold

A custom block or manifold from Servi can replace several stand-alone components or combine several functions thus optimizing operation with a reduction in installation time and possible leak points in the installation.

With our in-house design and production, we are 100% in control of the process from concept to ready product and can offer very competitive delivery times.

Please contact our in-house manifold expert Sonny Thoresen for a competitive offer.
