SUS304 Rapid Screw Fitting, Stud Coupling, Rapid Fitting for Plastic Tubing
Rapid Pneumatic Fittings Bulkhead Unions are widely used in liquid and gas tubing. It is suitable for advanced tech sectors, chemical industries as well as special environment of closure such as semiconductor equipment, medical instrument, and food process and so on.
Rapid Pneumatic Fittings Bulkhead Unions presents straight shape. Bulkhead Unions are designed to allow fitting body through a hole of equipment and object; the use of locknuts thread onto the body to hold it in place. Two ends apply flange design to make soft tube connection. It is used as the diversion port in pipelines.
The bodies are constructed of 316 or 304 stainless steel. Nuts are made of 303 stainless steel. CHIBIN bodies and nuts are precision machined to prevent tube falling off or broken. The soft tube can avoid to be cut for installation or replacement. The maximum pressure rapid pneumatic series can withstand is subject to thermoplastic tubes.
Features
- Durable and easy replacement.
- Precision machined bodies and nuts to prevent soft tube falling off or broken.
- The flange design isn’t necessary to apply seals and it won’t have leakage after inserting the tube.
- Material: SUS304, SUS316, Corrosive resistance
