ADPT SOCKETLESS/R6 STC

Description & Features

Manufactured from carbon steel with Dura-Kote plating for corrosion resistance, this straight adapter connects a 3/4" male NPTF thread to a 3/8" female Socketless/STC fitting. Part of Eaton Aeroquip's FF3089 Series, the ADPT Socketless/R6 STC is designed for hydraulic systems requiring reliable, leak-free connections at operating pressures above standard SAE ratings.

The STC (Socketless) female end is compatible with Aeroquip's push-on hose assembly system, making this adapter a practical choice for routing hydraulic lines where flexible hose connects to threaded ports. A rated minimum working temperature of -40°F extends its suitability to cold-environment applications. With hundreds of available styles within the FF3089 Series, this adapter supports design flexibility across a wide range of hydraulic circuit configurations.

Question by: Gene R on Jul 12, 2025, 8:38 PM
Got a 3/4 inch NPT port on a hydraulic manifold and need to drop down to a 3/8 push-on hose line. This the right adapter for that?
Answer by: Customer Support on Jul 14, 2025, 2:47 PM
That's exactly the use case this part covers. The male end threads into your 3/4" NPTF port, and the female STC end accepts a 3/8" Aeroquip socketless hose assembly. The NPTF thread form is designed to create a pressure-tight seal without sealant tape in most setups, and the STC push-on connection makes routing that flexible hose line straightforward once everything's in place.
