Catering for difficult connection applications
SKF Extension Pipes with Connecting Nipples
M4 extension pipe with connection nipple
Used to extend a high-pressure pipe with a
G 1 /4 nipple (e.g. SKF 227957 A) when the
connection hole has an M4 thread. The
extension pipe and connection nipple should
be ordered as separate items.
M6 extension pipe with connection nipple
Used to extend a high-pressure pipe with a
G 1 /4 nipple (e.g. SKF 227957 A) when the
connection hole has a M6 thread. The
extension pipe and connection nipple should
be ordered as separate items.
Valve nipple with extension pipe
This combination is intended to be used
between an oil pressure joint and an oil injector
(SKF 226271) when a thin wall thickness of
the pressure joint prevents the connection of
the injector directly to the joint. The valve
nipple is used to retain the pressurized oil
while the injector is refilled. The extension pipe
and connection nipple should be ordered as
separate items.
Extension pipe
This unit is used for connection to components
with a thin wall thickness, such as sleeves with
oil injection preparations. It is normally used in
combination with high-pressure pipes such as
SKF 227957 A.
