Product DescriptionA hammer union comprises of a thread end,
a nut end and a hammer nut which, when cinched up,
compresses a composite seal assembly thereby preventing
leakage. The seal assembly comprises a metal insert of
a size to pass into the seal groove of conventional hammer
unions and a small seal acting between the insert, the thread
end and the nut end. The small seal is conveniently an O-ring or
a Hammer Union Seal (Lip Seal) and is of a size that is
compressed when the seal assembly is inserted into the thread end
of the hammer union, thereby preventing the seal assembly from
falling out of the threaded end when it is inverted. Some
profiles such as Fig 2202, Fig 1004, Fig 1502, Fig 2002, Fig
602, Fig 1002 etc require a Hammer Union Lip Seal or an
'O'Ring depending on the Size of the Hammer Union.Detailed
