Want them to not leak? Put a nonfragmenting rupture disc at the inlet, with a suitable vent and/or telltale between the two in case the disc gets a pinhole and leaks. That is a major safety problem and cannot be ignored.

The seat tightness requirements for API-526 PSVs is probably a lot looser than most people think. The leak test calls for a piece of tubing to be connected to the discharge, and submerged in a beaker of water. The acceptance criterion is 40 bubbles of leakage per minute.

Also, seat tightness depends upon available preload-it is bad practice to operate any higher than 90% of set pressure.
