EDPM / NBR / VITON Seal elastomer with 316L stainless steel housing

Pipe Repair Clamps - 316L Stainless steel housing:

WA-RP-units are split for install and repair of existing pipe leaks.

Install Video waterline repair

repair-coupling-marinePipe repair clamps stop leaks in Steel, Cast Iron, PE or PVC pipes.

They enable repairs to be carried out while the pipes remains in service.

Suitable for emergency repairs or permanent repair to the pipelines.

EDPM and NBR seals are standard materials.

Viton and Silicone seals are available on request.



WA-RP repair clamps may be use on various operational pressures, 25 bar - 360 psi.

Pipe Repair Clamps WA-RC - L units for larger pipes.

Pipe operating pressures up yo 25 bar (360 psi)


WA-RC-L repair clamps are available i lengths up to 420 mm (16.50") long.

A pipeline remains in service during installation. Oil and gas pipelines, Marine piping, industrial pipes, fish hatchery, wastewater plants.pipe-repair-clamps

Split repair couplings reduce the installation time, they are light-weight made of 316L stainless steel material.


Lloyds, ABS, DNV GL and LRS.

Pipe Restraint Coupling 316L Stainless steel housing, WA-RC coupling


Restraint Pipe couplings, provide safe and strong axial pipe connections. 316L stainless steel housing provide corrosion resistant protection. Various seal types are available.

Restraint pipe couplings may be used on steel pipes, cast iron pipes, ductile iron and PVC pipes. WA-RC couplings are approved for industrial and Marine applications.

Grooving is not required, no flanges, no welding, or threading required. The restraints hold the pipe joints firmly in place.

Connectors for all pipe types.


Restraint couplings stainless steel meet the highest inspection requirements

Ideally suited for the shipping industry and waterworks


  • Join pipes of the same or dissimilar materials.
  • Axially restrained and axially flexible.
  • Axial movement and angular deflection compensation.
  • Water-hammer and vibration and structure-borne noise, dampening.
  • Detachable and re-usable.
  • Axial offset and angle compensation.
  • Leak-proof joints.
  • Pressure shock reduction.


EPDM & NBR (on request), VITON & SILICONE (on request)
TEMPERATURE 20 ˚C – 200 ˚C
MEDIUM: Water, Gas, Petroleum, Helium
PIPE MATERIAL: Steel, Cast Iron, PE, PVC



Pipe Restraint couplings provide high security by locking the pipes together under pressure. When the axial load of the pipe is increasing by internal pressure or external influence, specially shaped balls push hardened restraint teeth into the pipe surface.




Improved anchoring on steel DIP or cast-iron pipes. Angle of the teeth, maintain a grip on any surface like hot dip galvanized steel and other materials.


Pipe Couplings - Pipe connectors - Flex coupling joints

Pipe Couplings: for Steel pipe, Cast Iron pipe, HDPE pipe, or PVC Pipes.non-restrained-pipe-coupling-stainless

Pipe couplings WA-PC units offer flex for pipeline. Diameters up to 158" (4000 mm).

Housing is a stainless steel 316L material high strength design. WA-PC-Flex couplings offer weight savings over cast iron couplings.

Seal selection may be EDPM or NBR elastomer.

Pipe Restraint Couplings for HDPE Plastic, PVC, ABS Pipes

WA-Restraint coupling non-metallic pipes.plastic-to-plastic-coupling-restraint-conectors



Restraint griping rings secure pipes together and with not damage the pipe outside diameter.

Pipe restraint couplings for non-metallic pipes are available for American and International pipe diameter pipes.





  • Suitable for joining non metallic pipe material.
  • Advanced grip joint system.
  • Can Join pipes of dissimilar materials.
  • Leak-proof restraint joints.

Pipe Restraint couplings for dissimilar pipe materials - steel pipe to PVC pipe: or other non-metallic pipes.



PVC to Steel Restraint Coupling for differential pipe materials, steel and plastic. Seal materials are EDPM or NBR.

Distinctive teeth grips secures the steel pipe end and advanced grip design for non-metallic pipe.

When the axial tensile load increases by internal pressure or external influence, the grips push with greater force to the pipe surface.


Repair Clamps for small diameter pipe repairs, Copper, IPEX, ABS and other pipe types

WA-PC-SP couplings for 3/4" pipe and up.

No soldering, repair pipes while the pipe remains in service.

Joint small pipes quickly, no leaks permanent joints. Joint temporary pipe lines, easy dismantling.

Coupling Adaptability


Pipe deflection up to 2° (4°) in any direction.



couling-for-misalign-pipeMisalignment of pipe axis: Allowing misalignment of pipe axis, to a maximum of 2°.




Retrofitted of Pipeline: The large scale of clearance and tolerance make them an ideal construction device for retrofitting of pipe sections and fittings during repair work or change of pipeline direction.


pipe-coupling-t-jointT Fittings: Fitting (T), may rotate to any position and direction to accommodate application.


Valve Fittings:
Valve with plain ends, rotatable to any position.



Repair clamps and coupling connectors for pipes are used in many applications and different industries:

- Water treatment plants for secure pipe connections.
- Fish Hatchery operations connecting water feed lines.
- Fish Farming operations when flexibility and corrosion protection of 316L stainless steel if required.
- Compressed Air Lines.
- Plumbing connections.
- Temporary diversion lines for water works and street repair.
- T takeoff connections-fire extinguishing line supply lines.
- Heating Duct pipe connections.
- Waste water pipe replacement connections.
