OQC Series
■ Working Pressure up to 3,000psig (206bar)
■ Temperature rating -10 °F ~ 400 °F (-23 °C ~ 204 °C) with FKM O-Ring.
■ Stainless steel, Brass Construction
■ End Connection Size from 1/4" to 1/2"
Features
- Compact design.
- Quick and easy operation with Push-to-connect coupling
- No turn or tool is required when coupling and uncoupling.
- Wide variety of options are available for end connection.
- Single-end shutoff (SESO), DOUBLE-END SHUTOFF (DESO), and full-flow mode.
- SESO Stems have no valve and open while uncoupled from the body.
-DESO Stems have valves and shut off while uncoupled from the body. - SS316 and Brass Construction.

Identification: Valved Stem is visually identifiable with the red sleeve
Insertion Depth
To calculate overall lenght in the coupled position, subtract the insertion depth from any overall stem and body combination lengh.

Pressure-Temperature Ratings
O-ring Material & Temperature Ratings
Fluorocarbon FKM O-rings are standard for 316 SS bodies and DESO stem; for other materials, add an O-ring material designator to the Basic ordering number. Examples: QCSA-O-4T-KM-SS
Spillage and Air Inclusion
- Spillage is the system fluid amount escaping while DESO is uncoupled.
- Air inclusion is the amount of air entering the system while DESO is coupled.
Operation
■ Use filter ahead of quick-connects.
■ Use body and stem protectors or dust caps on uncoupled bodies and stems.
■ For coupling and uncoupling, align body and stem.
■ Perform coupling and uncoupling at room temperature.
■ Couple and uncouple quick-connects during system cleaning operations.
■ Support hanging hoses or other equipment to prevent side load.
■ Relubricate stem seal O-rings periodically.
▲ Caution:
■ Do not uncouple single-end shutoff stem under pressure.
■ Do not couple or uncouple at pressure exceeding 250 psig (17.2 bar)
■ Do not rotate quick connects while coupling and uncoupling
■ Do not insert foreign objects into uncoupled bodies or stems.

Full Flow Quick Connectors
- OQC Series Full-Flow quick connector consists of a single-end shut-off (SESO) stem and Full-Flow body.
- Full-Flow auick connectors are not automatically shutoff, must be depressurized prior to disconnection.
- To order a full flow body, select an applicable Basic Ordering Number, add "FF" and a material designator.
Stem & Body Protectors
- Stem and body protectors guard against damage and contaminants when bodies and stems are uncoupled.
- Protectors are not pressure-containing devices.
- Protectors include stainless steel lanyard and lanyard clamp.

Keyed Quick Connector
OQC keyed quick-connects provide a mechanical lockout system to prevent accidents caused by intermixing of different lines in multifluid or multipressure systems.
Features
- Applicable to control of multi-fluid and multi-pressure system.
- Keyed quick-connects are not coupled with any other OQC keyed quick-connects.
- If an attempt is made to couple unlike keys, the valve system will not open.
- Stems and bodies are eight color coded and key numbered for easy identification.
Keyed OQC Series Operation
- Select keyed stem and body in the identical OQC Series.
- For couoling, push the stem into the body until it clicks.
- For uncoupling, pull the body sleeve toward stem, and remove stem.
