What This Part Is

This is a slit valve door assembly for a 300mm Applied Materials SPD-configuration loadlock, sealing the wafer transfer opening between the loadlock and process chamber. It uses a Viton elastomer seal to maintain vacuum isolation during wafer transfers. The part is used in the gate mechanism that opens and closes to allow robotic wafer passage while keeping process environments separated.

Condition Options and Lead Time

Conditions we've observed on the market for 0040-84390: used. Availability in a specific condition changes week to week.

Typical lead time is 2-4 weeks after sourcing confirmation; parts already on a partner's shelf ship sooner. Every unit is inspected before shipment.

Inspect the Viton door seal carefully for compression set, cracking, or deformation before installation, as a degraded seal will cause vacuum leaks at the loadlock interface. Confirm the door mechanism and sealing surfaces are free of scoring or particulate damage.
