6.3.3 Assembly instruction for tubing and accessories manifold assembly
The manifold assembly has two ports 1/4"–28 UNF for liquid supply
connection.
The fluid connection fittings feature standardized plastic tubing or stainless
steel tubing with a diameter of 1/16" (1.588 mm), 3 mm 1/8" (3.175 mm). The
fluid connection fittings are composed of a threaded part, a lock ring and a
ferrule. The seal effect is obtained thanks to the plane ending of the ferrule and
the tube. The threaded part assures the required pressing force.
