Product overview

What it does, and where it fits.

A plain U bend traps liquid at its lowest point. Adding a bottom outlet turns that trap into a usable feature: the leg can be drained down, sampled, or fitted with an instrument.

The datasheet lists seven combinations with separate DN and DN1 bores and two dimensions, L and L1. Note that some combinations reduce the outlet — LSPUO2/1, for example, is a DN 50 U bend with a DN 25 outlet.

Features

Built into every unit.

  • 180° return with a drain or sampling branch at the base
  • Seven combinations, DN 15 to DN 80, with reduced outlet options
  • Separate L and L1 setting-out dimensions
  • Borosilicate 3.3 with beaded ends

Benefits

Why it earns its place in the line.

  • Removes the un-drainable trap of a plain U bend
  • Gives a natural low-point sampling position
  • 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

Applications & industries

Typical applications

  • Draining the low point of a glass run
  • Low-point sampling and instrument connections
  • Seal legs that must be emptied between batches
  • Distillation, absorption and scrubbing pipework

FAQ

Questions we are asked about this item.

The datasheet lists DN 80 only with a DN 25 outlet (LSPUO3/1). Tell us if you need a larger outlet at that bore and we will confirm what can be made.

The dimension down to the bottom outlet face. Use it with L to set the fitting out and to check the drain height above the floor or receiver.
