Did you know? DN 15

DN figures are nominal sizes, not measurements. DN 15 normally corresponds to a half inch thread, yet has neither 15 mm bore nor outside diameter.

Tee unions

Tee unions bring three lines together in one body, branching a run at right angles from the through tube. This category holds 106 items covering tube outside diameters from 4 LL (M8x1) up to 42 L (M52x2).

Sealing follows the cutting ring principle: cap nut, cutting ring plus the cone inside the body form a metal to metal seal on the tube surface, so no sealing compound takes part. Choice covers the extra light LL range, the light L range as well as the heavy S range, each in zinc plated steel or in 1.4571.

How to choose Tee unions

What matters when choosing: properties, comparison and typical applications.

Technical data

⚡25 tube sizes - from 4 LL (M8x1) through 12 L (M18x1.5) up to 42 L (M52x2), metric port threads from M8x1 to M52x2.

⚡Three ranges - extra light LL up to 12 LL (M16x1), light L up to 42 L (M52x2), heavy S up to 38 S (M52x2).

⚡Working pressure to 630 bar - tube 8 S of the heavy range reaches 630 bar, 25 S rates 400 bar, 28 L of the light range 160 bar, 12 LL 100 bar.

⚡Two materials - zinc plated steel for standard piping, 1.4571 as the corrosion resistant version, for example on tube 22 L or 25 S.

⚡NC type clamping ring - offered on tube 14 S in 1.4571, rated at 400 bar working pressure.

⚡Body without nut or cutting ring - single bodies available, among them tube 15 L, 38 S, 12 LL in zinc plated steel.

Applications

Tee unions serve hydraulic piping on machine tools, presses, power packs, wherever a pressure line or a return line splits toward two consumers. The heavy S range at working pressures up to 630 bar suits working lines, while the light L range covers return lines plus pilot lines. Small sizes from 4 LL (M8x1) branch gauge lines in tight spaces. Versions in 1.4571 go where zinc plated steel suffers from moisture or cleaning agents.
