Traditional welded rigid piping requires certified welders and hot work permits, and carries high risks of internal contamination and weld fatigue failure.
XYOON rigid pipe hydraulic fittings are precision-machined connectors for seamless steel tubing, available in bite-type compression, weldable and 37° flare configurations. Bite-type designs eliminate welding entirely, enabling fast, clean and leak-tight assembly for fixed heavy-industrial piping systems.
60% faster installation: Bite-type design only requires a standard wrench. No welding equipment or certified welders needed, drastically cutting on-site labor and shutdown time.
Zero internal contamination: No weld slag or oxide scale trapped inside tubes, eliminating pump/valve damage risks. No post-weld flushing required, ideal for high-purity circuits.
1M+ impulse cycle life: Precision ground sealing seats withstand continuous vibration and pressure pulsation, with better fatigue resistance than welded joints.
Full configuration range: Straight connectors, elbows, tees, reducers, bulkheads, plugs and caps, all sourced from one supplier with consistent quality.
Reusable & maintainable: Bite-type fittings support repeated disassembly and reassembly, making system modifications and routine maintenance fast and low-cost.

Q1: What is the difference between bite-type, weldable, and 37° flare fittings?
A: Bite-type (DIN 2353) requires no welding – a ferrule bites into the tube wall when tightened, ideal for fast, clean assembly. Weldable fittings are welded to the tube end, suitable for permanent connections in high-temperature systems. 37° flare (SAE J514) uses a flared tube end and nut, commonly used in North American hydraulic systems. Choose based on your system standard and installation preferences.
Q2: Can bite-type fittings be reused after disassembly?
A: The fitting body and nut can be reused. However, the ferrule is permanently deformed during initial installation and must be replaced with a new one upon reassembly to ensure reliable sealing.
Q3: What is the maximum working pressure for rigid pipe fittings?
A: Carbon steel heavy-series fittings are rated up to 630 bar (depending on size). Stainless steel fittings are rated up to 400 bar. Always verify pressure rating based on tube wall thickness and fitting specification.
Q4: Are Rigid Pipe Hydraulic Fittings compatible with tubing from other manufacturers?
A: Yes. Manufactured to DIN and SAE standards, our fittings are fully compatible with any seamless steel tubing that meets the required dimensional tolerances. We recommend using precision cold-drawn seamless tubes for optimal performance.
Q5: Do you support custom sizes and non-standard configurations?
A: Yes. We support custom sizes, special materials, and non-standard configurations based on customer drawings and specifications. Please contact our technical team with your requirements.
