According to the product information, the YJ6D series adopts a double ferrule connection structure and provides multiple end connection forms and thread standards. The product line includes different body styles and connector combinations to meet various piping layout and instrumentation installation requirements.
The product data states that the machining accuracy of the parts is high, which helps ensure accurate deformation of both the ferrules and the tube. The threads are hardened and polished to help improve service life and reduce thread galling. The nut threads are silver-plated to reduce the friction coefficient between the nut and the fitting body threads. For elbow fittings, the internal passage adopts a smooth radius transition to support stable fluid flow.
Each fitting can be marked with size, material, and heat number according to the product data.

제품 이점
- Leak-Free Two-Ferrule Design: The advanced double ferrule mechanism separates sealing and tube gripping functions, ensuring a positive, gas-tight seal that resists severe vibration and pressure surges.
- Extensive Material Options: To combat corrosive environments, we offer stainless steel tube fittings (316/316L, 304), Duplex 2205, Super Duplex 2507, various Alloys (400, 600, 625, 825, C-276), Titanium, Brass, and Carbon Steel.
- Global Standard Compliance: Our instrumentation tube fittings are manufactured to strictly comply with international thread and pressure standards, including ASME, ISO, SAE, and DIN.
- Anti-Galling Technology: The nut threads are silver-plated, and the body threads are specially hardened and polished, significantly reducing friction and preventing thread galling during assembly.
- Complete Traceability: Every single fitting is permanently stamped with the size, material grade, and heat code, ensuring 100% material traceability for critical projects.
- Smooth Flow Path: Elbow configurations feature radiused junction designs, which provide a smooth flow path, minimizing pressure drop and system turbulence.
