O-RING, FORK SEAL HOLDER - FITS LF HARRIS NEW PRODUCTION HOLDERS WITH 3MM (.125) GROOVE - FOR ORIGINAL US A TYPE
O-ring for the fork seal holder, sized for Harris-production A-type holders with a 3mm groove, PN 97-2119.
This is the O-ring that seats in the fork seal holder, sold under PN 97-2119, with the older reference H2119 still floating around in some parts books. The catalog notes it fits Les Harris-produced fork seal holders that carry a 3mm (.125 in.) groove, and specifically the original US A-type holder rather than other variants that came along later. It shows up across a run of front fork figures for T90, T100S, T100T, T100R, TR6R, and T120R, spanning catalog years 1967 through 1974.

The O-ring's job is simple: it seals the seal holder itself against the fork leg so oil stays where it belongs and road grit stays out. It's a small, cheap part to overlook, but a tired or wrong O-ring here is a common source of a fork leg that seems to leak even after you've replaced the main seal.
Because this one is called out for a specific holder groove dimension and the Harris-production A-type holder, don't just grab any fork O-ring off the shelf - check what holder you actually have before ordering. If you're not sure which type you've got, call the shop and we'll help you sort it out.
