Product overview

What it does, and where it fits.

The unequal tee takes a reduced branch straight off a glass run without needing a separate reducer, which saves a joint and a length of pipe. The datasheet covers 51 combinations from DN 25×15 up to DN 600×300.

Two dimensions are published for every combination: L, the centre-to-face along the run, and L1, the centre-to-face on the branch. Both are needed to set the fitting out — and note that unlike many ranges, L here does vary with the branch size on the larger bores.

Features

Built into every unit.

51 size combinations, DN 25×15 to DN 600×300
Reduced branch without a separate reducer
Separate L and L1 setting-out dimensions for every combination
Borosilicate 3.3 with beaded ends

Benefits

Why it earns its place in the line.

Completely inert to almost all process media — no metal pick-up and no contamination of the batch
Full visibility of the process along the whole line
Smooth, non-wetting bore that resists fouling and cleans easily
Excellent thermal shock resistance from borosilicate 3.3
Modular flanged construction — sections can be swapped without cutting or welding

Applications & industries

All dimensions in mm, transcribed exactly from the component datasheet. The datasheet lists LSPTU6/3 with DN1 = 100 and LSPTU6/4 with DN1 = 100; both are reproduced as printed — confirm the DN1 you need on the enquiry.

FAQ

Questions we are asked about this item.

L is the centre-to-face along the run, L1 the centre-to-face on the reduced branch. A reducing tee needs both to be positioned correctly.

That is how the datasheet prints it. We have reproduced the table exactly rather than correcting it; please confirm the branch bore with us before you fabricate pipework against that row.
