O-ring Seal (ORS) Manifolds

ORS manifolds & components are a simple, compact way of splitting and metering flow lines for any size of application equipment.

Tee & Feed Fittings

Center-fed tees, straight hose barb, 90° hose barbs & end cap feeds are available for plumbing your ORS manifold.

ORS End Caps, Plugs & Adapters

A number of end caps, plugs and adapters are available for both male and female ORS ports.

ORS Outlet Fittings

A variety of male ORS fittings are available to be used as outlet ports.

Push-in tube, hose barb and NPT-F fittings are available to use.

 ORS Check valve Bodies

Using check valve bodies greatly reduces fluid run on, and allow for orifice changing without leaking fluid.

There are two styles of check valve bodies, and a number of different shut-off options for both. [More below]

360° Range of Motion

All O-ring sealed fittings can be spun 360° without fear of leaking of pulling out.

This makes installation easy as the fittings pivot to where you need them to point.

Chemical Resistance

All ORS fittings are made out of glass-reinforced polypropylene with VITON® O-ring options, so there isn’t much that these manifolds can’t handle.

ORS Metering Orifices

O-ring seal metering orifices are accurate and large enough to make them easy to handle, so switching rates is easy.

Custom hole-size orifices and ISO-color coded orifices are available to match any rate required.

Simple Assembly

Since all ORS fittings simply plug into eachother and attach with the stainless steel u-clip, they do not need to be threaded at all.

For the ultimate ease of installation, lightly lubricate O-ring seals with liquid silicone when assembling.

O-ring seal (ORS) to ORS

An ORS male inlet with an ORS female port, allowing for an ORS metering orifice and ORS fitting to complete a manifold assembly.

ORS to Radialock Cap

An ORS male inlet with a radialock cap outlet (see Wilger Pricelist for options),  use with metering orifice (#40285-XX series) to complete a manifold assembly.
