Various types of vacuum hose
Vacuum bellows series
Selected high quality stainless steel raw materials hydraulic forming.
Imported helium mass spectrometer leak detector, full inspection of weld bead, suitable for LCD, semiconductor, aerospace, photovoltaic, biopharmaceutical, scientific research and other industries.

Vacuum Heat insulation bellows
Through careful design, strict manufacture and reasonable connection, the high vacuum insulated cryogenic liquid transmission pipeline produced by OBB® can minimize the cold loss, and the cryogenic liquid can pass through at-196 C without frost for 24 hours.

Explosion proof flexible tube
The explosion-proof flexible pipe produced by OBB® has passed MA explosion-proof certification. With our unique technology, the bellows and joint are connected by mechanical combination structure instead of lead (Pb) welding method, so this new product is environmentally friendly. Explosion-proof flexible pipe is used for connection of incoming and outgoing lines of explosion-proof electrical equipment or places where bending of steel pipe wiring is difficult.

Air conditioning hoses with Braiding
The shock absorber tube designed by OBB® is mainly used in cooling systems in refrigeration industry, such as air conditioning units, refrigeration devices, heat pumps, etc. It can prevent vibration transmission and has sound insulation function, can be compatible with conventional refrigerants, and can resist frost.
