Description
Leader ferrule Cock (Rubber Seat, PN 16), available 15 mm at PN 16. A ferrule makes the connection between a distribution main and an individual service line, and includes a means of isolating that service without disturbing the main. Taper BSPT threads seal on the thread itself, which suits duties where a parallel thread and washer would be awkward. Used by water utilities and plumbing contractors making individual service connections. The table above gives the catalogue reference and price for each size in the range.
