Is the HYCOA JR-33 a direct replacement for Kraissl transfer valves?

Yes. The HYCOA JR-33 "Will Fit" system is engineered as a direct drop-in replacement for Kraissl transfer valves in standard sizes. It matches existing flange bolt patterns and face-to-face dimensions, minimizing modifications to existing piping.

What is the main advantage of replacing Kraissl with HYCOA?

The HYCOA JR-33 uses a patented resilient Shoe Seal that provides engineered zero leakage — unlike Kraissl's metal-to-metal plug design which relies on fit and packing condition. The HYCOA design also requires no lubrication, operates at lower torque, and eliminates packing adjustments.

My Kraissl model number is not in this table — can you still help?

Yes. Contact Northeast Controls with your Kraissl model number, size, and pressure class and our engineering team will confirm the correct HYCOA JR-33 replacement configuration. Special sizes and configurations are available.
