Sealant injection equipment sends thick sealant through buttonhead fittings into a pressurised valve. Pump pressure must exceed line pressure, and every connected part needs the correct rating.

Hydraulic hand gun
BTR450D Hydraulic Sealant Gun
The BTR450D is an industry-standard hydraulic hand gun for portable valve servicing.
Its light, strong build suits chemical plants, refineries, wellheads and pipeline work.
Teams can choose universal adapters, couplers and hoses for each maintenance task.
Air-operated gun
BTR 550D Air Operated Sealant Gun
The BTR 550D supports larger valve service programmes across pipelines and plants.
- 10,000 PSI capacity
High-pressure output, about 690 bar, for hard valve maintenance tasks. - 100:1 pressure ratio
Air input produces controlled high-pressure sealant delivery. - Double-acting piston
Delivers sealant on both the forward and return stroke. - 63 lbs shipping weight
About 29 kg. Teams can move it between service sites. - Small and large valves
The design supports varied valve sizes within its operating capability.
Pneumatic pump systems
Count each stroke and control the quantity delivered
Customised stroke counters help teams plan injection amounts across many valve maintenance tasks.
Stroke counts give operators a clear record of sealant used for each task. Measured delivery helps teams avoid waste during planned maintenance work.
Repair kits
Plan the repair before technicians reach the valve
Choose the kit for the valve condition, planned task and site support.
Minor repair kit. The routine service kit for a gun: o-rings, seals and wear parts. Send your gun model and we will match the kit.
Major repair kit. The overhaul kit for a gun, with the wider parts selection. We supply two kits for each gun model.
High-pressure work needs rated equipment and safe fittings
Sealant injection is high-pressure work with set procedures and correctly rated parts. Every gun, hose, coupler and fitting must suit the pressure.
The fitting's internal check valve must never be removed while the valve remains under pressure. Read further valve maintenance guidance before planning any injection task.

Common questions
Sealant injection equipment questions
These answers help teams choose equipment before detailed maintenance planning starts.
What pressure does a valve sealant gun need?
The injection equipment must produce pressure above pipeline pressure at the valve. Engineers must also check that every gun, hose, coupler and fitting has the correct rating.
Should I choose a hydraulic hand gun or air-operated pump?
Hydraulic hand guns suit portable work where technicians control each injection stroke. Air-operated systems support larger maintenance programmes and repeated injection across many valves.
Can one sealant gun service every valve size?
The BTR 550D suits small and large valves within its stated operating limits. Teams must still check line pressure, valve condition, fittings and the sealant amount needed.
