Hydraulic Pressure
No failure report names the hydraulic pressure. 20 FAA approvals let 11 companies make a replacement hydraulic pressure, Kulite Semiconductor Prod INC holding the most (5).
Approved replacement parts 20 parts manufacturer approvals
A parts manufacturer approval (PMA) lets a company other than the aircraft's maker make a hydraulic pressure and sell it as an approved part for the models named. These are the companies holding such approvals for a hydraulic pressure:
For these models most: Piper PA-18 Super Cub (7), Boeing 747 (3), Dehavilland DHC-6 (2), Boeing 707 (2), Lockheed 382 (1), Airbus A330 (1).

Sources: the FAA's service difficulty reports since 1995 (a report is a part that failed and was fixed, as filed by an airline, repair station or owner; the count shows reporting as much as reliability) and the parts manufacturer approvals in the FAA's Dynamic Regulatory System. The part name is the reporters' and the approval holders' own words, reduced to the first plain words so that spellings meet.
