BENDING
The latest in CNC technology is utilized to bend all types of material from 1/8" through 3" O.D. Plug and ball type mandrels can be used to insure a smooth, wrinkle-free bend. utlizing Hexagon Metrology Tube Inspection systems, using the start of the art in inspection technologies which are utilized to check all bent forms for accuracy.
MECHANICAL O.R.F.S.
LEH is extensively involved with the cost-effective, highly reliable, Mechanical ORFS connection. LEH is involved with SAE directly in the evolution of this latest form in hydraulic applications. ORFS Mechanical Form originally appeared in section J1453 of the 1998 SAE Book of Standards. With a field population of over 30 million formed connections and ZERO failures!

MECHANICAL 4-BOLT FLANGE (Code 61 & Code 62)
LEH has developed cost-effective, reliable, Mechanically Formed Hydraulic Connections. LEH released a new revolutionary formed hydraulic connection in the Nexus Code 61/62. This process is proprietary to LEH and has been tested by the Milwaukee School of Engineerings, Fluid Power Institute, passing impulse testing at over 1,000,000 cycles as well as burst and vacuum tests at 6,000 psi working pressures. In our specialty NexusForm HD Code 62 we have achieved over 33,000 psi burst capability up to -20 (1 1/4") connector size.
