Application:
120406050 is the exhaust-valve stem seal for Perkins 403D-11,
403D-15, 403D-17, 404D-15, 404D-22 and 404D-22T three- and
four-cylinder diesels. It is therefore fitted to JCB 802-803, Cat
C1.1-C1.5, Linde forklifts, FG Wilson P13-5 to P22-5 generator
sets, Massey-Ferguson 1700E tractors and LiuGong 906/908
mini-excavators that share the same cylinder-head machining.
Technical specifications:
Nitrile-rubber lip seal with spring-loaded 8 mm ID, 14 mm OD, 7 mm
height; operating −30 °C to 120 °C in 15W-40 oil mist, withstands
0.5 bar crank-case pulse and 24 h salt-spray without loss of
elasticity. The lip is moulded to Ra 0.4 µm to micro-seal the 8 mm
exhaust-valve stem and prevent oil carry-over into the exhaust
port.
Material & performance features:
FKM/nitrile blend is asbestos-free and bonded to a steel carrier
for 25 % tear strength vs. cork substitutes; compression set <15
% after 70 h at 120 °C, providing >8 000 h leak-free life in
24/7 generator duty before replacement is required.
