Suck back valve performs two simultaneous functions. Being a normally closed valve, it requires air to actuate. When switching from the open back to the closed position, its unique design creates a vacuum on the discharge port and immediately "sucks back″ a predetermined amount of liquid. The adjustment knob on top of the valve gives excellent repeatability on the suckback volume. The suckback valve is the perfect solution for dispensing equipment to prevent dripping of solution from dispense nozzles. Photoresist, adhesive, acids, solvents, syrup and many other medias may be processed through this valve.

Teflon back up rings are designed to prevent extrusion in rubber O-ring sealing systems. Rubber O-rings serve as effective seals for dynamic and static applications in hydraulic and pneumatic systems equipment. The drawback of such O-rings is their tendency to extrude into the clearance of mating surfaces when subjected to increasing pressures. In order to overcome such drawbacks, the Teflon back up rings are used. There are three basic types of Teflon back up rings in use: single turn, multi-turn and solid configurations.

Teflon balls do not absorb water and can withstand temperatures to 550°F (288°C). It is useful in many laboratory procedures. It is not affected by any known acids or alkalies. It is available in a wide range of sizes.

Teflon coatings are formulated with special blends of fluoropolymers and other high performance resins to improve toughness and abrasion resistance. These coatings are applied as a single-coat, thin film, and non-stick finish. These are used throughout industry in military, space, commercial and consumer applications. Teflon has the lowest coefficient of friction of any solid material known. It is used as a non-stick coating for pans and other cookware.

Teflon discs are normally used to move heavy furniture easily without damaging the floor. These are used for moving large and heavy shelves, beds, sofa's, and desktops. The choice of the discs depends only on the weight, which is needed to move. It is available in various diameters.
