USA Lab Polypropylene Hose Connections – GL-14 & GL-18

These polypropylene hose connections are designed with a Viton rubber seal for secure use with GL-14 or GL-18 glass screw threads. Rated for working temperatures up to +110°C, they provide a reliable, chemical-resistant solution for connecting cooling or vacuum hoses.

With the option of straight or bent hose connectors, these fittings make setup simple—just screw the connector onto the glass thread instead of forcing Tygon tubing over a serrated glass joint.
