NT92 - Omega™” Dry Break Quick Coupling NT92 Series O-Mega™ Dry Break Quick Coupling is specifically designed to prevent radioacve resin valve blockage spillage during the disconnecng process. This unique coupling consist of a female end having a concave ball valve and a male end having a convex ball valve that are machined to eliminate any spaces between the ball valves. Added to the design is a cavity filler and a revoluonary O-Mega™ Sealing Process. The seal isin tension not compressed yielding a superior seal with greater strength and longer cycle life. Thorburn’s O-Mega™ coupling provides the soluon to resin blocking poppet type valve quick couplings which spill radio acve materials. NT9NT92 - Omega™ Easy to Operate The NT92 O-Mega™ coupling has an easy turn acon to connect and start the product flow. The valves will not open unl both coupling halves are connected properly. The coupling halves are first aligned and then connected with a push, followed by a quarter turn. There are no threads to damage by over ghtening and no failure prone cam and groove latch connecons to secure. The coupling halves are independent shut off ball valves that are controlled manually by rotang the valve handles in sequence providing unrestricted high flow in either direcon. NT92

• SeriesTLFP

Available with 150 psi (10 bar) & 300 psi (20 bar) rang Thorburn Flex offers safety spray shields manufactured with a nonporous, 100% PTFE mul-direconal TLFP material. THOR-SHIELD TLFP Spray Shields guarantee performance against harmful spray out and leakage regardless of severity and duraon of chemical exposure. Many materials used for spray shields, like PTFE coated fiberglass, can be weakened by challenging industrial environments and oen require monitoring. With the THOR-SHIELD TLFP Spray Shield, the body and drawstrings are all made of 100% PTFE. This ensures that the worker safety will not be jeopardized by degraded materials of a spray shield in the event of a spray out at a flange. Since THOR-SHIELD TLFP Spray Shield will be unaffected by even the most corrosive chemical environments, chemical capability tables do not need to be referenced. The translucent material used in the THOR-SHIELD TLFP Spray Shield allows safe and easy detecon of moisture leakage at a flange. If leakage does occur at the flange, the spray shield can be cleaned and reused without concern for weakening due to chemical aack. THOR-SHIELD TLFP Spray Shields can be used in a pH range of 1-14 and a temperature range of -340°F (-207°C) to 600°F (316°C). The versality and cost-effecveness of this type of spray shield allows it to be used in almost all industrial sengs such as marine, offshore, pharmaceucal, chemical processing, FDA approved, cryogenic, and clean room applicaons. THOR-SHTHOR-SHIELD TLFP FEATURES • Zero porosity • Unaffected by constant exposure to wet, chemical environments • Rated for 600°F (316°C) constant exposure • Unaffected by ultraviolet exposure • Fire and tear resistant • Translucent material allows leak detection • Drawstring is all-PTFE cord • Curl over inhibits side spray-out • Reusable • Available in many colors • Many options, such as drain nipples, are available • Custom sizes are available
