Compare each non-return valve connection pattern

The polypropylene non-return valves have separate connection entries: GS20063 lists 25, 32 and 38 mm, GS20064 lists 13, 20 and 26 mm, and GS20065 lists 25 and 38 mm. Use the entry for the exact reference; similar appearance or a shared diameter does not establish the same pattern.
