Common Safety Instructions for Products Listed in This Manual
⑩. A Shorter distance of plumbing with a wider bore is preferable at
vacuum system side. A long plumbing with a small bore may result in
slow response time at the time of releasing work-piece as well as in
failure to secure adequate suction flow rate.
⑪. In case of using non-PISCO brand tubes, make sure the tolerance of the
outer tube diameter is within the limits of Table 1.

7-1. Tube insertion (Push-in fitting)
①. Make sure that the cut end surface of the tube is at a right angle
without a scratch on the tube surface or deformations.
②. When inserting a tube, the tube needs to be inserted fully into the
push-in fitting until the tubing edge touches the tube end of the fitting
as shown in the figure below. Otherwise, there is a risk of leakage.
7-2. Tube insertion (Compression fitting)
①. Make sure that the cut end surface of the tube is at a right angle
without deformations or a scratch on its inner and outer surface.
③. After inserting the tube, make sure it is inserted properly and not to
be disconnected by pulling it moderately.
※. When inserting tubes, Lock-claws may be hardly visible in the hole,
observed from the front face of the release-ring. But it does not
mean the tube will surely escape. Major causes of the tube escape
are the followings; ① Shear drop of the lock-claws edge ② The
problem of tube diameter (usually small). Therefore, follow the above
instructions from ① to ③, even lock-claws is hardly visible.
