Genuine OEM Hirayama HAST chamber spare parts from Hastest Solutions, the authorized North American Hirayama distributor since 2002. Our San Jose, California facility stocks frequently-needed components for the PC-242, PC-422, and PC-702 HAST chamber series — including pressure sensors, temperature probes, gaskets, control boards, vapor generators, and replacement controllers (R8 and R9 generations).
Using genuine Hirayama spare parts preserves your chamber’s original calibration accuracy, JEDEC JESD22-A110 compliance, and warranty status. Aftermarket components frequently void manufacturer warranty and degrade test repeatability. Hastest ships directly from inventory in California, typically same-day or next-day in North America, with full installation support if needed.
If you don’t see the part you need below, call (408) 945-7861 or email contact@hastest.com with your chamber model number and serial number — we can source any Hirayama component for North American customers.
