18-Inch Compressed Air Distribution Manifold Block
The 236431 Compressed Air Manifold Block provides a central distribution point for supplying compressed air to multiple tools, hoses, or equipment lines. It can be used to build a custom air system for a spray foam rig, service vehicle, workshop, manufacturing area, or other compatible pneumatic application.
This listing includes the bare metal manifold block only. The open ports allow the system builder to select the regulators, gauges, valves, fittings, and plugs required for the intended setup.
The block measures 18 inches long, 3 inches wide, and 1.5 inches thick. It includes five 3/8-inch threaded ports across the top, two 3/8-inch threaded ports on the bottom, and one 1/2-inch threaded port on each end.
This block is also used as the foundation of the 348035 Complete Air Distribution Manifold Assembly. Customers who need the assembled version with regulators, pressure gauges, and outlet fittings should order part number 348035.

Frequently Asked Questions
Does this manifold block include regulators and gauges?
No. Part number 236431 is the bare manifold block only. Regulators, gauges, fittings, plugs, hoses, and mounting hardware must be purchased separately.
Is a complete manifold assembly available?
Yes. Part number 348035 is the complete air distribution manifold assembly built using this manifold block. It includes the regulators, pressure gauges, and connecting fittings used in the assembled configuration.
Can this manifold be used for applications other than spray foam rigs?
Yes. Although it is commonly installed in spray foam rigs, the block may also be used in compatible service-truck, workshop, manufacturing, and compressed-air distribution systems.
Can the outlets be set to different air pressures?
The bare manifold block does not regulate pressure. Individual regulators and gauges may be added when separate outlets need independently adjustable pressure settings.
How many threaded ports are included?
The block has nine threaded ports: seven 3/8-inch ports and two 1/2-inch end ports. The ports may be assigned as inlets or outlets based on the fittings and configuration selected for the system.
