Compression Fittings（Tube-to-Tube Connection Shape：Elbows）

Compression fitting is the general term for a pipe used to indirectly help connect one part to another. Compression fittings also have names such as joints and connectors. They are used to connect pipes and hoses. There are types that enable single-action attachment of the fitting end. They are known by names such as quick couplings. Black screw-in fittings are often used in standard pipes. Stainless steel fittings are highly corrosion-resistant, suitable for outdoor use. Fittings with inserts improve part strength and durability. Besides stainless steel, compression fittings are made of materials such as brass and alloys (65% copper and 35% zinc). The right compression fitting for the application should be selected by considering factors such as material, shape and type.

90° Elbows - Bulkhead, Compression Fittings, N2701-LN Series

Brennan Industries

Brennan's Instrumentation Tube Fittings provide leak-proof, torque-free seals at all tubing connections. Brennan's Double-Ferrule and Single-Ferrule Tube Fittings are reusable several times and can withstand heavy impulse and vibration in both vacuum and pressure systems Exhaustive tests have proven that the tubing will yield before a Brennan Double-Ferrule joint starts leaking.

Brennan Instrumentation Tube Fitting Features:
· Self-aligning
· Work on thick and thin wall tubing
· Resist vibration
· Work on a variety of tube materials
· All components are made of the same material for thermal compatibility and corrosion resistance
· Resist temperature cycling
· Compensate for the variables encountered in the tube and materials
· Do not significantly reduce flow area

Performance
· Work in vacuums, as well as at low and high pressures
· Seal at low cryogenic temperatures, as well as elevated temperatures rated for the tube
· Seal consistently over a wide range of temperature cycling
· Seal repeatedly under both make and remake conditions
· Resist pressure beyond the tubing burst point

Assembly
· Use geometry rather than torque for uniformity of make-up. (To complete the joint, it requires only a 1-1/4 turn after snug-tightening.)
· Do not require disassembly and inspection of ferrule swaging at every make-up
· Do not require any special tools for assembly
