PTFE Fittings for tubing are designed to make fast, neat, leak-proof assemblies. Fit is only specified to the tube OD and any ID is useable. Tubing is simply inserted and the nut tightened. No special tools or equipment are required to assemble. All wetted parts are PTFE. Nuts are made of Halar or Kel-F fluoropolymers for added strength.
PFA fittings are designed for handling corrosive or ultra-pure fluids in applications where contamination is a concern. Constructed of 100% virgin PFA, these fittings combine high purity with the robust performance of compression-style fittings.
PFA fittings are easy to use and need no special tools for installation. Designed for a variety of fluid handling applications, are ideal for gas or pneumatic conditions in applications that do not require flared connections.
Stopcock Valves are precision machined devices that function in much the same way as a ball valve. When the handle points in the direction of flow, the valve is fully open; when the handle points perpendicular to the direction of flow, the valve is fully closed; and at the 45º position the valve is halfway open and thereby has a metering effect on the media flow.
The Stopcock features an all PTFE wetted surface design. The design is ideally suited for harsh chemical and corrosive media and environments. Polytetrafluoroethylene (PTFE) is also well suited to clean room and deionized water applications.
