Tubing Connectors: Temperature Range -40°C to 200°C

Q: What are the main types of tubing connectors?

The three primary types are compression fittings (using ferrules), push-to-connect fittings (for quick assembly), and threaded fittings (NPT, BSPP). Each type offers different advantages for pressure, maintenance, and installation requirements.

Q: How do I select the right tubing connector material?

Material selection depends on fluid compatibility, pressure requirements, temperature range, and environmental conditions. Stainless steel offers corrosion resistance for harsh environments, brass provides good machinability for standard applications, and engineered plastics suit chemical resistance needs.

Component Specifications

Definition

Tubing connectors are mechanical fittings designed to create secure, leak-proof connections between tubing segments in fluid distribution systems. They serve as critical interface points in distribution manifolds and tubing networks, enabling proper fluid routing, pressure maintenance, and system modularity. These components must withstand operational pressures, temperature variations, and chemical exposure while maintaining dimensional accuracy and sealing performance.

Working Principle

Tubing connectors operate by creating a mechanical seal between tubing ends through compression, threading, or push-to-connect mechanisms. They utilize sealing elements (such as O-rings, ferrules, or gaskets) that deform under compression to fill microscopic gaps between mating surfaces, preventing fluid leakage. The connection mechanism (threaded, compression, or quick-disconnect) provides the mechanical force needed to maintain this seal under system pressure and vibration.

Materials

Stainless steel (304, 316), brass, aluminum alloys, engineered plastics (PTFE, PEEK, nylon), with sealing elements made of Buna-N, Viton, EPDM, or silicone rubber.
