Instrumentation Fittings
Precision Connections for Industrial Systems
At YDB Valves LLP, our tube fittings are engineered for reliable, leak-free connections in demanding industrial environments. These fittings play a critical role in fluid handling systems by linking tubing runs to pipes, valves, instruments, and other components in a wide range of applications. Our portfolio includes high-quality stainless steel fittings designed for exceptional strength, precision, and longevity across instrumentation, hydraulic, pneumatic, and process control systems.
What Are Tube Fittings?
Tube fittings are mechanical components used to join tubes and facilitate fluid or gas transfer within a system. They are essential in connecting tubing to other tubes, pipes, or equipment, ensuring secure and corrosion-resistant joints with minimal leakage. Constructed with precision in accordance with international quality standards, YDB fittings provide consistent performance in high-pressure and industrial environments such as petrochemical, power, water treatment, chemical, and pharmaceutical facilities.
Applications
YDB tube fittings are used extensively in sectors that demand robust fluid control solutions, including:
Instrumentation and measurement systems
Hydraulic and pneumatic installations
Chemical and petrochemical processing
Power generation
Water treatment and utilities
Oil and gas distribution
Each fitting is produced under strict quality control and testing procedures to ensure performance that meets global standards for safety, strength, and reliability.
Key Features and Benefits
Our fittings employ robust ferrule and compression designs that deliver tight, dependable seals, reducing the likelihood of leaks even under extreme conditions.
Manufactured from premium stainless steel and compatible materials to resist corrosion and wear, ensuring longevity in harsh environments.
Designed for straightforward assembly, YDB tube fittings allow for quick and secure installation without special tools while maintaining superior connection strength.
Available in a range of sizes, thread types, and configurations to accommodate diverse industrial requirements and system layouts
Suitable for instrumentation systems, hydraulic and pneumatic networks, process plants, and fluid control installations where precision and reliability are paramount.

Heat Traceability
Stainless steel 316 Tube fittings are heat code traceable back to the original mill heat from which it was made.
Pressure Rating
YDB Tube fittings are rated for working pressure higher than the tubing recommended in tubing data table as shown below. However, tubing should not be used above its maximum allowed working pressure.
Tubing Selection
Stainless steel 304 and 316 fully annealed seamless tubing according to standard ASTM A213 or ASTM A269 or equivalent, are suitable for use with Tube fittings.
The tubing should be compatible with the process fluid, pressure and temperature.
For good performance of Tube fittings, the tubing should be reasonably round, free from nicks, scratches, the surface finish should be good and tube ends are squarely cut and must be free from burrs. The hardness of tubing as desired is 80Rb; the maximum allowed by ASTM is 90Rb.
