Doing some spring cleaning and selling some spares I no longer use or need. IIRC these were bought from BZB, they’re all stainless and I don’t think a single one cost us less than $175 + S&H. These will definitely fit the Unistat 815/915 and any other chiller which uses the M30x1.5 metric connection for connecting to coolant output and return. The 3/4" ones are unused but we used others like them with 1.5" tri-clamp fittings to adapt them to the hoses and vessels we were using the chillers on.
Have 2x of the M30 x 3/4" female pipe thread. Never installed to either a chiller or had anything threaded into the pipe thread. $250 shipped for the pair or $140/ea shipped
Have a single M30 x 1" female pipe thread. This one was installed but taken apart when we changed a setup, threads are clean. May have a bit of marine anti-seize on the M30 side. $130 shipped
Buy all 3 for $300 shipped
