Advantages Of Rubber Sealing Test Plugs

A round, knurled cap for hand-tight sealing.
Captive cap.
The plugs’ rubber cores are made to the right hardness to give easy iInsertion and a fast seal.
Tried and tested for over twenty years.
"Selfseal’’ test plugs- the professionals choice.
Very practical, conserves energy, sold worldwide.

Easy To Install

The test plug is screwed into a BSP welded socket or a threaded boss, threaded pipe tee, valve or vessel.

Quick And Easy To Use

Unscrew captive cap, push the pressure gauge/manometer or thermometer probe through the test plug, take your reading, remove probe and replace cap.

Versatile

Obtain pressure and temperature readings, determine flow rate. Plugs can also be used to inject fluids into the system.

Low Cost

Test plugs are extremely economical. The price of two brass test plugs is generally cheaper than a gauge cock, or pressure gauge.

For Heating Installations
For Chilled Water Installations
For Process Services

For measurement of flow rate two test plugs are used, one on each side of an orifice, calibrated valve or an item of equipment of known pressure loss/flow characteristics. Pressure differential is used to determine flow rate.
In any system of pipe-work requiring to be balanced or regulated it is essential to be able to readily determine (a) Temperature (b) Flow rate
Test plugs incorporated at strategic points in the piping system are a quick and economical method of obtaining such data.

Provides Accurate Data

As direct contact is made with the liquid or gas in the system and if the correct gauge or thermometer is used, a greater accuracy is given. Our non-mechanical test plugs do not rely on springs and will not scale up.

Reduces Commissioning Time

Because of the small size and low cost of test plugs, they can be fitted virtually anywhere in the system where pressure or temperature measurement may be required, giving the commissioning engineer new methods for balancing and commissioning with greater accuracy and with real saving in site time.

Fixed Instruments

Permanent pressure gauges and thermometers in pipework are traditionally, restricted to where they would be visually acceptable rather than most useful.
Test plugs can be fitted in restricted piping. However they must be positioned to enable probes to be used to take readings.
A test plug fitted close to an instrument can also be used to check on the accuracy.
"Selfseal" test plugs comply with C.I.B.S.E code W 1994 water distribution systems (D.O.E. M&E 100). Standard Specification for low temperature hot water.
Recommended by the National Engineering Specification Limited Y11 Pipeline Ancillaries and BS7350 1990.
