<p>The present invention provides a flow restrictor coupling 10 and a method of forming a flow restrictor coupling. The flow restrictor coupling 10 comprises a hollow tubular member 12 having at a first end thereof first means for engagement with an end of a first pipe and, at a second end thereof, second means for engagement with an end of a second pipe, wherein said hollow tubular member 12 is arranged to couple said first pipe to said second pipe and to provide for fluid communication therebetween, said flow restrictor coupling 10 further being arranged to present at least one aperture 26 in a wall of said hollow tubular member between said first and second ends, the aperture 26 having selectively variable dimensions for control of fluid flow therethrough.</p> |
