Straight-Flow Junction Blocks
Use these junction blocks to organize and separate multiple lines in your system. They have threaded holes that allow air, water, or hydraulic fluid to flow straight through the block. They have mounting holes, so you can mount from the side.
Anodized aluminum junction blocks are lightweight with good corrosion and wear resistance.
316 stainless steel junction blocks have excellent corrosion resistance and can handle fuel, gasoline, coolant, and other harsh substances.
Use a plug (sold separately) to close off any unused inlets and outlets.

Right-Angle Flow Junction Blocks
These junction blocks have threaded holes that allow air, water, or hydraulic fluid to flow at a 90° angle through the block. Use them to organize and separate multiple lines in your system. Junction blocks are anodized aluminum, which is lightweight with good corrosion and wear resistance.
Use a plug (sold separately) to close off any unused inlets and outlets.
