PRVs are an absolute must…
Anyone care to do the math and show their work on the expected pressure for 36g of THCA in a 1liter vessel at 130C?
Then point out the problem with putting 358g in there (less than 1/2 full).

Note: A two ft x 2” triclamp spool is reasonably close to 1liter (1.1l ish) given 1.87in ID.
Two inch high pressure clamps should handle 800psi at 250F. You’ll want ptfe gaskets.
