DESCRIPTION:
Model: SC-1 One-Way Inline Check Valve
Vehicles: Heavy-duty trucks, tractors, trailers, and listed M35A3 and M911 military vehicle applications
• Valve Type: Single one-way pneumatic check valve
• Supply Port: One 1/2"-14 NPT female
• Delivery Port: One 1/2"-14 NPT male
• Overall Length: 2.03"
• Body Type: Straight inline configuration
• Operating Temperature: -40°F to 250°F (-40°C to 121°C)
• Function: Permits airflow in one direction while preventing reverse airflow
• System Use: Air brake, air suspension, reservoir, compressor discharge, and auxiliary pneumatic circuits
Applications:
Designed for commercial and military vehicle pneumatic systems requiring directional airflow and separation of air-pressure circuits. It is typically replaced when pressure bleeds backward through the valve, air passes in both directions, or an internal restriction reduces forward airflow.

A cross-reference listing means this part may be a suitable replacement for the listed part numbers. Always verify fitment before installation.
IMPORTANT INSTALLATION NOTES:
✔ Confirm the system uses one 1/2"-14 NPT female connection and one 1/2"-14 NPT male connection.
✔ Install the valve in the correct direction of airflow.
✔ Support the hex body while tightening to prevent housing or thread damage.
✔ Apply air-system-compatible thread sealant without allowing sealant to enter the airflow passage.
✔ Pressurize the system and verify forward airflow, backflow prevention, and leak-free connections.
