Integrated Pistonô combines a piston made from cold-drawn carbon steel, a machined bearing with wide surface area, and a seal matched to the application requirements into a single unit. The bearing is molded onto the piston core. The product reportedly reduces side-load effects and guards against contamination and cylinder drift in industrial machinery as well as mobile equipment. Uses include low-, medium-, and high-pressure hydraulic cylinder applications.

Single-, double-, and four- and six-passage versions of RU series rotary unions reportedly facilitate hydraulic control in work-holding applications. The single-passage rotary couplers directly mount to SAE ports. The twin-passage unions operate two single-acting circuits or one double-acting circuit. The four-passage model operates four single-acting or two double-acting cylinders. Six-passage units accommodate six single-acting or three double-acting cylinders. Both standard and manifold mounting are possible.
An integral forced-feed oil lubrication system is a recent addition to the Microvac 412J pump. This new system can enhance the pump's oil delivery capabilities, is self-contained, and is powered by the main pump shaft. The latter eliminates the need for additional motor leads, valves, or reservoirs that can leak. Useful in long pump down or gas handling applications, the system is O-ring sealed to the Microvac 412J to preclude leakage even at high oil feed pressures.
