17J02 Series

Design Features

Self Locking

Threaded closure locks automatically when nut detent mechanism engages the detents along the face of the body. Assembly and disassembly are performed by hand without tools.

Meets Military Requirements

Coupling design has been qualified to all applicable military specification requirements for flexible fuel coupling systems with service pressures of 125 PSIG (operating), 250 PSIG (proof), and 375 PSIG (burst), plus surge pressures to 270 PSIG and temperatures from -65°F to 450°F (except -72AB & -80AB, see factory for pressure data).

Self Bonding

Electrical bonding to class "S" of MIL-B-5087B is automatically provided when the coupling is assembled.

Flexible

Axial adjustment is shown in table. Angular misalignment is ±4° for full coupling.

Coupling Flanges

The coupling flanges are mechanically attached (swaged or welded) to tube ends. Information about tooling and installation procedure is available from Hydraflow upon request.

Non-captive

The 17J02 coupling is non-captive; it can be installed over flanges or pump ends with machined-on flanges.

Product Notes

1. Coupling flanges and seals are not furnished with these assemblies and, for clarity, are shown in phantom outline. Seal material is selected and seals are separately procured by user. For additional information see notes 1 & 2 under "Ordering Information".
