Easy and safe assembly of BOLA Laboratory Screw Joints!


BOLA Laboratory Screw Joints consist of a screw cap, a V-ring, a tapered ring and a sealing ring. The size of the GL thread and the outer diameter of the tubing or tube are decisive for the choice of the appropriate laboratory screw joint.

BOLA Laboratory Screw Joints can easily be assembled by hand:

• Push the screw cap on the tubing or tube.
• Push the V-ring, the tapered ring and the sealing ring on the tubing or tube (our tipp: sharpen the tubing end or cut it diagonaly. The single rings can now easily be put on the tubing).
• Tighten the screw cap on the GL-threaded neck - done.
