Carbon steel 90 degree elbow adapter with male NPTF and female JIC threads

Eaton

Eaton Aeroquip 2250-16-16S 90° Elbow Adapter 1-11-1/2 NPTF to 1-5/16-12 JIC

SKU CH-BQ10-BT558

A 90-degree elbow adapter connects 1-inch NPTF male threads to 1-inch JIC female threads for hydraulic systems up to 500 psi

  • 90-degree elbow enables tight routing in hydraulic systems
  • Male NPTF to female JIC connects dissimilar thread standards
  • Carbon steel construction rated for 500 psi working pressure
  • SAE J514 compliance ensures dimensional interchangeability
  • 3-inch overall length fits standard assembly envelopes

Eaton Aeroquip 90° Hydraulic Adapter

This Eaton Aeroquip 2250-16-16S adapter connects a male NPTF thread to a female JIC swivel in a 90 degree elbow configuration. It is built for hydraulic hose assemblies requiring a directional change at the connection point. The carbon steel construction suits industrial and mobile hydraulic systems. Installers needing a compact, high-pressure elbow will find it matches the SAE J514 standard.

Thread specification decides fit

The critical specification is the thread pairing: a 1-11-1/2 NPTF male end and a 1-5/16-12 JIC female swivel end. Both ports are sized for 1 inch nominal pipe and hose. A 500 psi pressure rating applies to the assembled joint. Verify that the mating components share these exact thread forms and sizes before ordering, as mismatched threads will leak or fail under pressure.

Simple installation with thread care

Installation requires standard wrenches to engage the hex flats on the adapter body and the swivel nut. Apply appropriate sealant or tape to the NPTF male threads only; the JIC seal relies on metal-to-metal flare contact. Common issues include cross-threading the fine 12-pitch JIC nut, over-torquing the carbon steel body, or omitting sealant on the tapered NPTF side, any of which can cause leaks.

Questions about this item

How does the 90-degree elbow affect routing in a tight hydraulic circuit?

The 90-degree bend lets you change direction sharply without extra fittings, reducing leak points and saving space in confined engine bays or machine frames

What practical limit does the 500 psi rating place on system pressure?

The assembly must not see pressure above 500 psi, so relief valves and pump settings need to stay at or below that figure to avoid fitting failure

What clearance is needed to install the 3-inch overall length?

You need at least 3 inches of straight run plus wrench swing room for the 1-inch NPTF male and 1-inch JIC female hexes to tighten without hitting adjacent components
