We supply glass U-Bend tubing, traditional tubing manipulated according to your requirement Precision Bore Tubing Precision Bore tubing has applications in Electronics and in the Laboratory. It allows you to have a much tighter internal diameter than is offered by standard tubing. We offer tubes with a tolerance as tight as 0.1mm.
When replacing the glass tube you must also replace the rubber sealing cones at either end of the tube. Moncrieff offer the widest range of cones to compliment our tubes. Available to suit 1/2", 3/4" and 5/8" Outside Diameters.
How to install Water Level Gauge Tubes
1.) Hold fitting rigidly in true alignment: so they won't turn when packing units are tightened. 2.) Provide metal washers so nuts can be tightened without twisting the packing or the tube.
3.) Provide positive, but not excessive, clearance between glass, packing nuts, and bearing washers.
4.) Keep glass short enough to allow for expansion.
5.) Tighten packing nuts enough to prevent leakage, but not so much that you hinder expansion or contraction.
6.) Use rubber packing for low and medium pressures, but use graphoil packing: Packing Sleeves for high temperatures or pressures.
7.) Use cylindrical or conical packing.
