Straight crimpable hydraulic hose fitting with 3/4 inch hose I.D. and 1-5/16-12 female JIC swivel thread

  • Product typePart
  • Straight crimpable fitting enables quick hose assembly
  • 3/4 inch hose I.D. matches common hydraulic lines
  • 37° JIC swivel thread provides leak-free seal
  • SAE 100R1 and 100R2 rated for high pressure
  • Trivalent chromium zinc finish resists corrosion longer

Fitting for 3/4 Inch Hose

This Eaton 1AA16FJ12 is a straight hydraulic hose fitting designed for a 3/4 inch internal diameter hose. It suits technicians assembling or repairing high-pressure hydraulic lines on mobile or industrial equipment. The crimpable connection creates a permanent seal for reliable fluid power circuits. Buyers needing reusable or push-on style fittings should select a different part.

Female JIC Swivel with Trivalent Zinc Finish

The fitting features a 1-5/16-12 female JIC swivel nut with a 37 degree seat angle for metal-to-metal sealing. A RoHS compliant trivalent chromium zinc coating protects the steel body from corrosion. It meets SAE 100R1, SAE 100R2 and GH793 standards for dimensional and performance consistency. No additional sealant or thread tape is required on the swivel face.

Crimp Installation Requires Correct Tooling

Installation demands a compatible crimp machine and the correct die set for hose dash size 12 to achieve the specified 2.91 inch overall length. Under-crimping leads to hose blow-off while over-crimping damages the tube reinforcement. Verify hose compatibility with SAE 100R1 or 100R2 construction before assembly. The part is not field-serviceable once crimped.

Questions about this item

Will the crimp connection on this 1AA16FJ12 fitting need re-crimping after extended service?

The crimpable design creates a permanent hydraulic seal; re-crimping is not a standard maintenance step unless the hose assembly is replaced.

What pressure limit governs continuous operation of the 1AA16FJ12 straight fitting?

The fitting meets SAE 100R1 and SAE 100R2 hose standards, so the hose pressure rating determines the sustained-use limit.

Does the trivalent chromium zinc finish on the 1AA16FJ12 affect heat dissipation during all-day hydraulic cycles?

The ROHS-compliant finish provides corrosion resistance without altering the steel fitting’s thermal conductivity in continuous operation.
