<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> |
