Applications
The Graco 104641 Bulkhead Fitting is used wherever a fluid line must pass securely through a wall, barrier or panel within spray systems, mobile rigs or fixed fluid-handling modules. It supports applications such as proportioner pump manifolds, mobile spray trailer assemblies, and industrial finishing stations requiring robust, serviceable connection points.
Performance Advantages
- Facilitates reliable through-panel connections with minimal leakage risk
- Supports high-cycle and high-flow systems with secure mounting and sealing
- Reduces service downtime by enabling quick access and replacement without full disassembly
- Enhances system integrity by maintaining consistent fluid path alignment and sealing under vibration or motion
- Improves layout flexibility by enabling clean bulkhead integration of hoses or tubing
Maintenance Tips
When servicing the bulkhead fitting, inspect the seal faces for wear, ensure the panel mounting nut is secure, check for corrosion or thread damage, and verify fluid or air connection integrity. Replace the fitting if mounting becomes loose, sealing surface shows grooves or the connection exhibits leaks or significant wear.
Frequently Asked Questions
A bulkhead fitting is installed through a panel or equipment wall to allow fluid or air lines to pass through while maintaining a sealed, secure barrier — ideal for spray rigs or fluid-handling cabinets.
Replace it if you notice fluid seepage, mounting looseness, thread damage, or a compromised seal — all of which may impact system performance or safety.
Clean the mounting hole, insert the fitting body, secure the backing nut, ensure the seal face is tight to the panel, and tighten per manufacturer specs — avoid over-torque and ensure line alignment.
It’s compatible with spray system modules, proportioner cabinets, mobile fluid rigs and other equipment requiring sealed through-panel fluid or air line connections — effectively used in Graco systems.
