Abstract

1339242 Pipe couplings J W MULLINS 9 Feb 1972 5999/72 Heading F2G In a line-tapping service valve, e.g. for a refrigerant gas main 42, a Vee block 30 has grooves 32, 34 of different depths in its opposing faces, so as to accommodate mains of different sizes. The size range may be further increased by using spacer rings (66, Fig. 4, not shown).
