1976 Honda CB550K · Gas Tanks, Caps, Petcocks & Parts Buying guide

Compare the tank connection and cap hardware

One petcock gives an M20 × 1.5 connection; the other listing gives a different reference without a thread specification. The chrome cap lists a gasket and hinge hardware, while latch parts are separately offered.

Do not transfer one petcock specification to another

The 16950-341-671 replacement expressly lists an M20 × 1.5 connection. The 16950-374-671 replacement does not state a thread size in its description. Compare the actual tank connection and ask about the second unit if necessary; its shared model application does not fill in that missing specification.

Separate the cap from its latch order

The chrome cap lists a gasket, hinge pin and E-clip. The separately listed latch assembly includes a chrome latch, return spring, mounting pin and C-clip. Compare both contents lists with the fitted tank hardware before assuming a new cap supplies a new latch as well.

Common ordering questions

Do the two petcock listings establish identical threads?

No. Only the featured 16950-341-671 replacement states an M20 × 1.5 thread. The other petcock description gives 16950-374-671 without a thread specification. Confirm its connection instead of borrowing a specification from the neighboring listing.

What hardware comes with the chrome cap?

The cap description lists a gasket and a hinge pin with E-clip. The latch assembly is separately listed with its own contents. Compare the parts needed on your tank before adding separate seal or latch purchases.

Is OEM-type the same as a genuine Honda cap?

The product is described as an OEM-type chrome cap with a Honda replacement reference. That description does not establish genuine Honda manufacture. Compare its supplied hardware and application with the fitted tank before choosing it.
