Hoses and TubingAll VektorFlo® hoses are intended to operate up to 350 bar (35 MPa) working pressure.Hoses are typically used to feed entire fixtures, medium size hoses are for feeding small fixtures or single devices.

NOTE: Use of standard rubber hoses and end fittings can hamper the action of many devices due to excessive end fitting restrictions. If you choose to purchase hoses from another supplier, be sure that hose diameters and end fittings are not causing ex ces sive restrictions.

Hydraulic Junction ManifoldsConvenient, cost effective con nec tion point for mounting quick connect fittings on fixtures and pallets.Provide a secure interface when connecting between rigid steel tubing and flexible hose.High strength steel, careful attention to detail in design, and extensive testing ensure re lia bil ity at working pressures up to 350 bar (35 MPa).

Two separate flow paths in single manifold sim pli fies hydraulic con nec tions and reduces the number of com po nents required in double acting systems.Wide spacing between ports allows use with elbow

and tee tube fittings.Can be converted to an 8 Port Single Path unit. Manifold Block

I-2

Rotating unions are a rotary connection, feeding pressure to fixtures while allowing full 360° rotation of the fixture with or without pressure.A machine or independent indexer may do this indexing. Rotating unions allow “live” hydraulic power to be supplied to fixtures during the machining cycle.

Single, dual, quad and 6 path models are available to fit your application. G 1/4 models are required for major fluid distribution and all remote valve systems. G 1/4 models may be used on double acting systems and small single acting systems where speed of retraction is not critical. Most units may be either man i fold mounted or used with standard fittings. Slip Rings are electrical rotary connections which can be operated with some models below.

The leak free design eliminates the need for a drain or vent line required by standard industrial models. This feature also reduces the demand for pressure present in industrial models that can cause pump cycling.

All units include internal bearings to increase lifeunder loaded applications. Quad path models are often installed in machine doors to feed two in de pen dent dual path models on fixtures, making VektorFlo® the choice for all of your machine clamping needs. Integral mounting holes and multiple plumbing options make VektorFlo® designs easier to use than specialized larger in dus tri al model.

Solidly bolt into place either the shaft or the housing component of the rotary union; not both. Mount the opposing component using a cableway or similar anti-rotation device to allow for some movement in the event of misalignment.
