The fittings described in this page are particularly indicated for connecting vacuum cup holders to their manifolds and in all those cases that require a connection to vacuum sources via smooth flexible hoses with internal diameters of 4, 6 and 9 mm, which is the maximum allowed for a vacuum hose

with no internal reinforcement. These are semi-rapid fittings. The hose is fixed by manually screwing the reeded bush with no need for keys. The threaded connections are male and female, according to the requirements. The range is completed by L and T-type fittings and caps with O-rings.
