When process accuracy and leak‑proof performance are non‑negotiable, engineers turn to Twin Ferrule Instrumentation Fittings. At Satvij International—an IATF 16949:2016 and ISO 9001:2015 certified manufacturer in Faridabad—we design and produce twin‑ferrule tube fittings that keep critical oil‑and‑gas, petrochemical, and power‑generation systems running safely at high pressure.
What Are Twin Ferrule Instrumentation Fittings?
Twin ferrule fittings (sometimes called double‑ferrule fittings) consist of a body, front ferrule, back ferrule and nut. When the nut is tightened, the front ferrule creates a tight seal on the tube while the back ferrule grips the tubing for vibration resistance. The result is a reliable, reusable, zero‑leak connection without welding or flaring—ideal for instrumentation and impulse‑line applications up to 6000 psi and beyond.
Why Specify Satvij International Twin Ferrule Fittings?
1. Precision CNC / VMC Machining
All components are produced on advanced CNC, VMC and Traub machines to maintain tight dimensional tolerances and concentricity, guaranteeing perfect alignment and repeatable sealing every time.
2. Premium Materials & Certifications
We machine our twin‑ferrule fittings from 316 / 316L stainless steel, carbon steel and special alloys. Full material traceability is provided along with EN 10204 3.1 certificates and in‑house pressure‑test reports.
3. Comprehensive Size Range
We stock tube OD sizes 6 mm – 25 mm and ¼" – 1" with BSP, BSPT, NPT, UNF, and ISO thread options. Custom sizes up to 42 mm are available on request.
4. Rigorous Hydrostatic & Pneumatic Testing
Every batch is hydro‑tested up to 1.5 × design working pressure and helium‑leak tested to confirm bubble‑tight performance—essential for critical hydrogen, nitrogen, steam and chemical service lines.
5. Global Compatibility
Our nut and ferrule geometry is fully interchangeable with common international twin‑ferrule systems, allowing easy drop‑in replacement without tube modification.
