Instrumentation Tube Fittings Manufacturers in India
Instrumentation tube fittings work on the principle of the mechanical grip that creates an accurate, high-integrity, and leak-proof seal even without the need for welding. Typically, these fittings consist of a head, front ferrule, back ferrule, and a nut. When the nut is tightened, the back ferrule grips the tubing, and the front ferrule creates a seal opposite the appropriate body and tube surface
This double-ferrule workflow ensures reliable sealing, even in high-pressure and vibration-prone environments.
Specifications of Instrumentation Tube Fittings
- Compression-relying sealing eliminates welding or threading; building installation is rushed and void.
- Truth tolerances in the ferrules secure repeatable and persistent performance.
- They are intended to maintain structural integrity during thermal cycling, approach vibration, and pressure fluctuations.
Fittings are generally an integral part of the systems that can be considered an inseparable part used in instrumentation lines, system control systems, pneumatic systems, and hydraulic applications, where accurate flow control and monitoring are fundamental.
At Doshi Impex India , our instrumentation tube fittings are manufactured to meet international material standards such as ASTM, ASME, and so on. This ensures they perform under severe requirements while maintaining dimensional genuineness and sealing competence.

FAQs
Q1. What are the distinguishing points comparing compression & flare tube fittings?
Compression fittings use a ferrule to compress & seal the tube, suitable for pressures which can be slightly higher than usual. Flare fittings involve flaring the tube closure, offering prime sealing for high-pressure applications.
Q2. What components are optimal for corrosive environments?
SS 316/SS 316L and alloy steels provide wonderful corrosion resistance in harsh chemical or marine environments.
Q3. Can Doshi Impex manufacture custom fittings?
Yes, we offer customized manufacturing as well as production activities to meet unique measurements or components that are most significant for the projects.
Q4. How do I know which size to order?
Fitting size depends on the tube outer diameter and application pressure. Our technical team can assist with sizing and arrangement.
Q5. Are your fittings compliant with international standards?
Yes, our products comply with pertinent ASTM, ASME, JIS, UNS, DIN standards, & so on. As we are certified with the ISO standards, our whole manufacturing facility follows the standards of the ISO to deliver the best.
