The UnitedBuilt Choice 6410-20-10-O is a straight male-to-female orb adapter with -20 Male ORB x -10 Female ORB. Use it to join the specified hydraulic connection types without changing the mating equipment ports.
Compare both the fitting end and its mating connection, including thread form, size and sealing surface. Dash sizes describe nominal connection sizes; they are not the measured outside diameter of the thread. This listing is for the adapter, not a complete hose assembly.
Match the connection to the job
The straight configuration connects the two ends in line, so hose routing and access can be planned around the existing ports.
| Feature |
Benefit |
| Connection-specific design |
Select by the complete end type and dash-size combination, not by appearance alone. |
| Straight male-to-female ORB adapter |
Matches the stated connection layout when the port clearance and mating parts are correct. |
| O-ring boss connection |
Uses the appropriate O-ring and port geometry rather than tapered pipe-thread interference. |

Before ordering
Confirm the supplied fitting's pressure and temperature limits, material compatibility and suitability for the hydraulic fluid before installation. A series number and dash size do not establish those ratings. Isolate and depressurize the circuit before work, and follow the equipment and fitting supplier's installation procedure.
| Check |
What to confirm |
| End 1 mating part |
Corresponding female SAE ORB port. An O-ring at the male stud seals in the matching SAE straight-thread port. This is O-ring boss, not ORFS face seal. |
| End 2 mating part |
Corresponding male SAE ORB stud with suitable O-ring. An O-ring at the male stud seals in the matching SAE straight-thread port. This is O-ring boss, not ORFS face seal. |
| Inspection |
Check threads, sealing surfaces and any O-ring for damage or contamination. Do not force an incompatible thread or seat. |
