NOS

No box

Condition: Genuine NOS (New Old Stock) — brand new, never installed or used.
Details: Original vintage 12 LB radiator pressure cap in bright factory yellow zinc finish, stamped "REMOVE SLOWLY / PRESSURE CAP / 12 LB".
Fitment: Classic 1960s–1970s Nissan / Datsun models using a 12 LB cap (such as Datsun 1200, 510, 521, and early 240Z).
Note: As expected with 45+ year old storage, the rubber underside gasket shows age cracking (see photos), making it ideal for show display or a fresh rubber seal. (replace rubber)
