Pipe Couplings - Pipe Restraint Couplings - Pipe Repair Couplings

WA Pipe Couplings 316L stainless "Fits all American or International pipe sizes".

EDPM / NBR / VITON Seal elastomer

Repair couplings WA-RP- UN type are split for repair or joining of existing pipes.

They are used to connect and/or seal damaged metal and plastic pipes. Featuring “cut flanges” on the underside of the fitting, this type of coupling can be easily fastened around a leaking pipe to seal a fracture.

See repair coupling install Video

Repair couplings WA-RP-UN make a permanent repair to a pipeline while the line remains in service.


Pipe Repair clamps may be used on Steel, Cast Iron, PE or PVC Pipes.

EDPM and NBR seals are standard materials, Viton and Silicone seals are available. SS repair coupling operational pressures are suitable for PN 16, 10, 6 (230 psi, 145 psi, 87 psi) lines.












Split repair couplings are suitable for emergency and permanent repairs.

Repair Clamps large diameter pipe up yo 25 bar (360 psi)


WA-RC-UN-L Repair clamps up to 420 mm (16.50") long.

Pipeline remains in service during installation. Oil and gas pipelines, ship boat piping, industrial pipes, fish hatchery, wastewater plant piping











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

Split repair couplings accept slight profile differentials such as copper pipe couplings when soldered pipe joints leak.

Ideally suited for the shipping industry and waterworks

Restraint Coupling 316L Stainless steel, WA-RC-UN coupling


Restraint couplings for pipes with stainless steel housing provide safe and strong axial connection restraints.

Certificates for shipping and industry solutions. They may be used on steel pipes, cast iron pipes, ductile iron and PVC pipes.

Butt end joint connections no grooving, flanges, welding, or threading required.

Pipes are locked together with progressive anchoring as pressure increases. Designed has a universal pipe end restraint connector for all pipe types.

  • 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



Restraint coupling design that offers high security by locking the pipes together under pressure. When the axial tensile 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 hard surfaces stainless steel or cast-iron pipes. Angle of the teeth, maintain a grip on any surface like hot dip galvanized steel and other materials.

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

Pipe couplings WA-PC-Flex for pipe diameters up to 158" (4000 mm), provide security and ease of installation.

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

Seal selection may be EDPM or NBR elastomer.

Couplings for Plastic, PVC, HDPE Pipes

Pipe couplings WA-RC connect non-metallic pipesplastic-to-plastic-coupling-restraint-conectors



Advanced grip rings with distinctive restraint teeth holds non-metallic pipes together without damaging the surface of pipe.

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





  • Suitable for any pipe material
  • Compatible with any traditional jointing system
  • Joins pipes of the same or dissimilar materials
  • Leak-proof joint for most pipeline media
  • Quick and simple repairs of damaged pipes without service interruptions
  • Axially restrained or axially flexible couplings available

Axial Restraint couplings steel pipe to PVC: or other non-metalic pipes.



Restraint Coupling for differencial pipe materials, seals are EDPM or NBR.

Pipe couplings for combination material pipes are used to connect plastic pipes to metal pipes.

Designed with distinctive cut teeth that engages into the plastic pipe without damaging the surface of the plastic pipe at one end and a grip ring with special design teeth for steel pipes.

When the axial tensile load of the pipes are increasing by internal pressure or external influence, will push hardened teeth into the pipe surface.

The depth of the anchoring’s teeth under pressure is approximately 0.1 to 0.3 mm.

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



3/4" pipe and up.

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

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

Plumbers tool box for instant jointing of pipes, no welding or soldering.

Coupling Adaptability


Angular deflection: cover angular deflection of pipes 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.
