Axial pipeline coupling

Pipe Couplings - Restraint Couplings - Repair Clamp Couplings

WA Restraint Couplings, with 316 stainless housing "Fits all American or International pipe sizes".

AISI 316 (A5) - EDPM / NBR / VITON

Restraint Coupling 316L Stainless steel Body.


Westatlantic Class restrain pipe couplings provide safe and strong axial restraint.

Plant certificates for shipping and industry solutions for use on steel pipe, cast iron pipe, ductile iron and PVC Pipes.

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

A UNI restraint design with progressive anchoring, lock the pipes together under pressure. Designed has a universal pipe end restraint connector for all pipe material.



Restraint stainless steel couplings that meet the highest inspection requirements, Lloyds, ABS, DNV GL and LRS.

Ideally suited for the shipping industry and waterworks


  • Join pipes of the same or dissimilar materials.
  • Axially restrained and axially flexible.
  • Compensates axial movement and angular deflection.
  • Dampens water-hammer, vibration and structure-borne noise.
  • Detachable and re-usable.
  • Compensates axial offset and angles.
  • Leak-proof joint for liquids, gas and for solids.
  • Reduces pressure shocks.

TEMPERATURE 20 ˚C – 200 ˚C
MEDIUM: Water, Gas, Petroleum, Helium
PIPE MATERIAL: Steel, Cast Iron, PE, PVC



Restraint coupling design offers high levels of 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 teeth into the pipe surface.

Achieve improved anchoring on hard surfaces like thin-walled stainless steel or cast-iron pipes. Oblique angle of the teeth, maintains a grip on any surface like hot dip galvanized steel and other materials.



The gasket seal is patented and uses the latest techniques in sealing.

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

WA FLEX pipe couplings for pipe diameters up to 158" (4000 mm).

FLEX couplings provide security and ease of installation.

Stainless steel and high strength 316 stainless steel design, offers weight savings over cast iron couplings. Less manpower, quicker installation, cost savings.









Pipe end stainless steel couplings that meet the highest inspection requirements, Lloyds, ABS, DNV GL and LRS.

WA Split Repair couplings for existing pipe.

Repair couplings make a permanent repair to a pipeline while the line remains under pressure.

They installed quickly and safely while the pipeline remains in service.

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

EDPM and NBR seals are standard materials, Viton and Silicone 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. Avoid costly reinstatement work caused by water damage.


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.

Repair stainless steel couplings that meet the highest inspection requirements, Lloyds, ABS, DNV GL and LRS.

PVC/HDPE to PVC/HDPE - or to Steel Pipes

Westatlantic class pipe couplings connect all pipe types and deferential pipe materials













Grip (restraint) couplings for non metallic pipes (HDPE, PVC, Plastic type pipes) are used to connect non-metallic pipes or steel pipes to non-metallic pipes. The specially designed gripring with its distinctive grip teeth holds the pipes together without damaging the surface of the non-metallic pipe.

During installation of the coupling compensation beads/grooves are used, stainless steel inserts required in other types of restraint cpouplings is no longer required. Inserts only needed in vacuum pipes.

Grip couplings for non-metallic pipes are available to restrain most American and International pipe diameters.

Models are suitable for new installations and retrofit, whether on a building, ship or process plant.


  • Suitable for any pipe material
  • Compatible with any traditional jointing system
  • Joins pipes of the same or dissimilar materials
  • Leak-proof joint for liquids, gas and for solids
  • Quick and simple repairs of damaged pipes without service interruptions
  • Installation and sealing principle consistent throughout the range
  • Axially restrained or axially flexible available

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.
