Please confirm the RA1K10-4-6 fitting’s compatibility with your aircraft using these documents:
Rapco’s fittings for aircraft pneumatic instrument systems feature a smooth curve design to minimize the loss of vacuum or pressure over standard AN or MS fittings. Their wide, unrestricted passages help maintain flow rate at altitude and increase the service life of your dry air pump since it causes less restriction on the pneumatic system.
