1.  Structural Design Advantages


Core design targets British standard pipe systems, addressing “poor compatibility between British standard threads and tapered seals, prone to leakage under high pressure”:


Sealing Structure: Employs a “37° taper + British standard thread dual seal” configuration. The fitting body incorporates a 37° internal taper that mates with the flared end of a rigid pipe (or the cutting edge of a ferrule) to form a metal-to-metal seal. - metal-to-metal seal. Paired with British Standard Parallel Thread (BSPP) or Tapered Thread (BSPT), the threaded section can optionally incorporate sealant/PTFE tape for auxiliary sealing, meeting medium-to-high pressure sealing requirements.


Core Components: Primarily consists of the fitting body (with BSP threads and 37° taper), locking nut, and ferrule (included in some models). Certain straight/right-angle models integrate anti-loosening structures to minimize nut loosening caused by vibration.


2. Key Features


Compatibility: Fits British pipe sizes (e.g., 1/8“, 1/4”, 3/8" corresponding to pipe OD), compatible with carbon steel/stainless steel rigid pipes meeting BS EN 10305-4 standards. Also compatible with some JIC 37° flared fitting installation tools (e.g., flaring tools, torque wrenches), reducing cross-standard usage costs.


Working Pressure: Maximum working pressure 350-400 bar (varies by pipe diameter: up to 400 bar for smaller diameters, 350 bar for larger diameters).


Fitting Material Options: Carbon steel, stainless steel.
