Ask A Question

Description & Features

A JIC 37° female swivel fitting in a 45° elbow configuration, the Aeroquip Fitting Perm Thermo is designed for use with -4 dash size hose and built from carbon steel for durability in demanding hydraulic environments. The female swivel end measures 0.4375 inches and mates with standard JIC 37° connections, while the elbow geometry accommodates routing where straight fittings are not practical.

Finished with Dura-Kote plating, this fitting delivers strong corrosion resistance suited to industrial hydraulic service. The design is system-engineered to extend hose assembly service life and support maximum uptime. With a hex size of 0.56 inches and a drop dimension of 0.3300 inches, it integrates cleanly into standard hose assembly configurations. Package weight is 0.16 lb.

Question by: Hubert T on Feb 7, 2026, 7:03 AM
Will this fitting hold up alright in a hydraulic system that sees some pretty tough conditions?
Answer by: Customer Support on Feb 9, 2026, 6:42 AM
Dura-Kote plating gives this Aeroquip fitting good corrosion resistance, so it should last well even when exposed to harsh conditions in hydraulic applications.
