P=Plain end; S=short round thread; L=Long round thread; B--Buttress thread;

a: Labels are for information and assistance in ordering.

b: Nominal linear masses (col. 4) are shown for information only.

c: The densities of martensitic chromium steels (L80 Types 9Cr and 13Cr) are different from carbon steels. The masses shown are therefore not accurate for martensitic chromium steels. A mass correction factor of 0.989 may be used.

d: Buttress casing i s available with regualr, special clearance coupings or special clearance couplings with special bevel.
