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.

O-ring Seal Materials Buna-N or VITON®
U-clip Material Stainless Steel
ORS Fitting Material Glass-reinforced Polypropylene

ORS Components

All O-ring seals are Buna-N by standard. VITON® O-rings are also available.
#20525-00 ORS x 1" NPT x ORS Tee

Tee & Feed Fittings

Center-fed tees, straight hose barb, 90° hose barbs & end cap feeds are available for plumbing your ORS manifold.
#20521-00 ORS End Cap

ORS End Caps, Plugs & Adapters

A number of end caps, plugs and adapters are available for both male and female ORS ports.
#20511-00 3/8" Hose barb ORS Fitting

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.
#20551-00 ORS to ORS Check Valve Body for ORS Manifolds and Flow Indicators

 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]

O-ring Seal Fitting Benefits

360° Range of Motion

#20511-00 3/8" Hose barb ORS Fitting

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

#20574-00 4 outlet O-Ring Seal manifold

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

ORS metering orifices with ISO Color coding for flow rate

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

O-ring Seal Manifold Examples, showing simple feed in and out options, with the option of check valves. Ideal for Liquid fertilizer kit distribution.

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) Check Valve Bodies

Wilger makes two styles of check valve body, with 4 different shut-off options available for each

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.

#20551-00 ORS to ORS Check Valve Body for ORS Manifolds and Flow Indicators

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.

#20561-00 ORS to Combo-Jet Cap Check Valve

Diaphragm Check Valve & Shut-off Options for ORS Check Valve Bodies

Wilger's standard 10PSI diaphragm check valve. Also available in 4PSI and 15PSI options.

Diaphragm check valve

Available in 4PSI, 10PSI (standard) and 15PSI versions
Fairprene diaphragms standard. VITON® diaphragms available.
Wilger's Manual ON/OFF diaphragm check valve

Manual ON/OFF check valve

When ‘ON’, it acts as a 10PSI* check valve.
When ‘OFF’, it turns off the flow completely to that body (*4PSI/10PSI/15PSI options are available)
Fairprene diaphragms standard. VITON® diaphragms available.
Air-Off Module for Combo-Rate Nozzle Bodies

Air-Off check valve

Acts as a standard diaphragm check valve, but when an attached air line is charged, it will turn OFF the flow to that body.
Fairprene diaphragms standard. VITON® diaphragms available.
Wilger bodies all share the same module thread, which is compatible with other precision farming options. (i.e. PWM solenoids)

Open thread option

Sharing the same thread as all COMBO-RATE® modules, the open thread is compatible with PWM or other precision ag systems.
