Different in construction to a conventional cylindrical inflatable stopper, the Cone Pipe Stopper is far more versatile.
The Bypass Cone Pipe Stopper is ideal for when stopping the flow is not possible in a pipe, drain or sewer. This durable bypass stopper allows you to drain off the water through a PVC type pipe used in the middle of the stopper.
The Trelleborg Megaplug is a special inflatable plug for pipe diameters larger than 580mm.
Ideal for air testing, water testing and flow stopping. Maximum diameter 440mm.
Suited to create a diversion or bypass when working in the pipe line.
The Pronal Inflatable Cylindrical Stoppers are available in sizes ranging from 100 - 1200mm.
Ideal for flow control (blanking off and bypassing) or air testing.
Whether you need to carry out air testing, water testing, flow stopping, fluming or over-pumping, Vetter expandable cylindrical stoppers are an effective and convenient solution.
Available as blank or test plugs, the oil and acid resistant rubber protects against aggressive fluids.
If the standard sealing pipe can not be used due to high back pressure, then these high pressure pipe stoppers are recommended.
Where an inflation pump or even a compressed air cylinder is not sufficient we can now offer a mobile diesel compressor.
The Water-Gate™ barrier is unique in the way that once rolled out, it self deploys. It uses the weight of the water to hold the water back. The water lifts the top of the barrier and weighs the base down, forming a seal.
This service allows the client to start, record and complete a pipe line test remotely from the Stopper Specialists website.
Our test flanges are available in sizes ranging from 40mm-1600mm, all to suit NP16 pipe work. Various fittings and connections are available to suit the specific application. These include ballvalves, fire hydrant connections and non-return valves.

These one-sized plugs are available for internal pipe diameters of 50mm to 315mm, with each plug covering a range of 20mm.
Ideal for water transference, our 2.5" Fire Hose with instantaneous fire hydrant couplings is available in lengths to suit your requirements. Standpipes are fitted with backflow protection (double check valve) to prevent contamination of the water supply network.
When pressure testing polyethylene pipelines we recommend the introduction of aqua foam swabs ahead of the water collumn to assist in removing any air, especially where the pipeline undulates.
Assists in overcoming ovality and irregular sized pipelines.
The RAK has been developed as a direct result of the building regulations (BSEN 752:2008) stating persons must no longer enter reduced access environments.
Designed for use when air testing drainage pipes to a standard air test of 100mm of water over air. Milltest Air test stoppers are very light and easily transported, making them ideal for testing awkward to reach locations.
A durable aluminium testing plug with a single rubber seal, suitable for carrying out water and air tests in all types of pipes. Also available in pressed steel.
Multiple compression points around perimiter of the plug enables seal expansion in localised areas.
The Eesiseel range of inflatable PVC plugs have ridged bodies to ensure a good seal even in difficult conditions.
Stopper Specialists offer nylon air bags with either a Schrader valve or a gascock. These bags are ideal for areas where the access opening is smaller than the test diameter or where the test is some distance from the point of access. They can be supplied with any length of inflation hose.
These packers are suitable for repairing damaged pipelines and joints. They are available with a bypass in a range of sizes from 150mm – 1200mm.
The packers have been designed to be used in conjunction with a patch repair kit, to give a convenient and cost effective way of completing localised repairs to pipes, drains and sewers.
These packers are made of a rubber sleeve that is vulcanised onto metal heads. The interior tube lets the water flow off during the repair work.
The permanent and simple solution to repairing pipes using no-dig technology.
Sealing Tubes are used for a fast and temporary leak sealing of pipe bend and difficult-to-access pipe connections.
Vacuum drainage bags use suction to attach to tanks or containers so no need for belts or tightening chains.
The Leak Sealing Lance Set can seal holes at a distance with a remote placement and inflation lance.
Drainage pipe sealing bags are perfect solution for leakages on pipe connections
Mini leak sealing bags are used for sealing leaks in small tanks and barrels.
Large Leak Sealing Bags are used for fast and temporary leak sealing. They are used on tanks, in large pipes and containers of all shapes and sizes.
The storm-drain sealing set is used to quickly seal roadside storm-drains in the event of chemical spill and to keep contaminates out of drainage system.
Sealing bandages are used for sealing pipes
from the outside.
The new Airtest Stopper covers pipes ranging from 300mm to 700mm with only two sizes.
The all new PressureTest+ app brought to you from Stopper Specialists. The app works alongside a Bluetooth enabled Data Logger to prepare, record and capture pressure test data in real time.
The Direct Injection Chemical dosing unit can be used in a variety of applications. It can be used to chlorinate pipelines, increase residual chlorine levels and dechlorinate pipelines.
The High Pressure Chlorination and Dechlorination Unit can handle flows of up to 1,200 litres per minute while still dosing sodium hypochlorite at 20ppm.
The Pressure Test Box is a control unit through which a pressure test is managed and recorded.
This range of stoppers allows the execution of leak-tightness controls, and the conduct of operational maintenance, both onshore & offshore.
The Air-Lance is designed for the safe loosening of soil around buried pipes, ducts and cables.
