Compression Fittings（Tube-to-Tube Connection Shape：Partition Unions）

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.

Union - Bulkhead, Compression Fittings, 316SS, PUS Series

Junkosha

Usable across a broad temperature range. No wear and tear to tubing as a result of the over tightening of cap nut, etc.

[Features]
· Because the product consists of SUS316, which has high corrosion resistance properties, it can be used in a wide temperature range, at both low and high temperatures.
· Designed especially for fluorine polymer/nylon resin tubes, so the tube does not rupture due to excessive tightening of cap nuts, etc.
· No abnormality in the connected part unless the tube is ruptured.
· The tightening torque of the cap nut does not need to be managed.
Fitting uses SUS316, so it resists rust.

Connector - Bulkhead, Quick Seal, Brass, UCT Series

Nitta

Three-item system made up of brass specification panel touch connector (mm size) fitting unit, nuts and sleeves, and integrated fitting unit and insert. Excellent negative pressure performance.

[Features]
· The tube is connected by PushOne®.
· No need for jigs nor tools to connect the tube.
· Electroless nickel plated.
· There is little deterioration of the surface and elution of copper ions into the fluid is prevented.
· Flame-retardant resin (equivalent to UL94 V-0 standard) adopted.
· Non-combustible PBT resin is used for the materials.
· Equivalent to UL94 V-0 standard, with superior self-extinguishing properties.
· Can be used in environments in which sputtering occurs.
· The R screws are sealed, and thus there is no need to wrap them with sealing tape.

Union - Bulkhead, Compression Fittings, N2700-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
