Aeroquip R5 Hose
Original
Aeroquip R5 Hose
R5 Hose is a Society of Automotive Engineers (SAE) Specification - there is no specific "inventor" of this hose type, although we would argue that Peter F. Hurst - the founder of Aeroquip played a large part in its development.
Only a few of the hoses listed below are true SAE R5 spec - at a Carlton Hydraulics, we tend to use the term R5 to cover all the hoses that use the R5 re-usabe fittings.
When is a dash size not a bore size? ….. When it's an R5 hose

General Application
Hydraulic systems with petroleum, crude, fuel and lubrication oils, gasoline & air.
Hose Fittings
Historically the R5 hose had re-usable fittings and this is the core of Carlton Hydraulics' stock. Bubble crimp fittings were then developed but due to crimp die constraints these were not adopted by Carlton Hydraulics. One piece pallet swage R5 fittings are now available on request.
R5 Reusable Fitting Types:
BSPP, BSPT, JIC, SAE inverted flare, NPT, ORFS, SAE 3000, metric light (L Series).

Re-usable Hose Assembly Tips:
Fittings with no hex on stem require a mandrel (or male for assembly).
Step 1
Cut hose square to length required using a cut-off wheel.
Clean hose bore.
Step 2
Put socket in vice. Screw hose counterclockwise into socket until hose bottoms. Back off 1/4 turn.
When assembling long lengths of hose, it may be preferred to put hose in vise just tight enough to prevent from turning, and screw socket into the hose counterclockwise until it bottoms. Back off 1/4 turn.
Back off FC300, FC350 and FC355 hose 1/4 to 1/2 turn.
Step 3
MALE ENDS: Push assembly tool into nipple.
SWIVEL ENDS: Tighten nipple and nut on assembly tool.
Lubricate nipple, mandrel and inside of hose liberally. Use heavy oil or Danfoss 222070 hose assembly lube.
Step 4
MALE ENDS: Screw nipple clockwise into socket and hose.
Leave a 1/32” to 1/16” clearance between nipple hex and socket.
SWIVEL ENDS: Screw nipple clockwise into socket and hose.
Leave 1/32” to 1/16” clearance between nut and socket.
