Gas pressure regulator coupling arrangement

In combination with a gas pressure regulator and a gas meter, an arrangement for coupling an outlet pipe of the gas pressure regulator to an inlet opening of the gas meter for fluid communication therebetween, wherein the gas meter inlet includes a cylindrical wall extending into the gas meter from the inlet opening, the arrangement comprising:

• a planar surface on an exterior wall of the meter, the planar surface surrounding the inlet opening of the meter, said exterior wall including a plurality of internally threaded blind holes extending into said exterior wall from said planar surface;
• a plate having a planar surface adapted for contact engagement with said exterior wall planar surface, said plate having an opening surrounded by said plate planar surface and adapted for alignment with said meter inlet opening when said plate planar surface is in contact engagement with said exterior wall planar surface, said plate further having a plurality of through-bores each adapted for alignment with a respective one of said plurality of blind holes when said plate opening is aligned with said meter inlet opening;
• a cylindrical tube extending from the plate planar surface and adapted for insertion into the inlet opening, the tube having a circumferential groove on its outer surface;
• and
• a resilient sealing ring adapted for receipt in said groove;
• wherein said plate is formed integrally as part of the outlet pipe of said regulator.
