RECOVERED

Originally a 76-6000Ns case.               Now a 76-4800Ns case.

RECOVERED

Snap ring grooves are machined with a chamfered edge on the inside of the groove. The helps to prevent bulkhead or nozzle o-ring damage during installation.
This does not affect the snap ring’s ability to hold pressure.

TIP: Use internal spiral rings instead of snap rings They are available as medium to medium heavy thickness and will fit Loki, AMW snap ring grooves.
Better holding retention.
No tool is necessary for installing.
A $1.00 paint can key is used to remove the ring.
