STEM PIPE ASSEMBLY ELGi | 015404147 & 990404840

Upgrade or overhaul your compressor's internal lines with the Royal Stem Pipe & Separator Tube Assembly Set, engineered to perfection by Royal Air Component. This heavy-duty dual-component kit forms the structural backbone inside the air-oil separator block housing where your spin-on separator filter safely mounts.

Structural Integrity & Functionality

This kit brings together the internal Separator Tube / Pipe (Part No: 990404840) and the interlocking Double Fitting Nipple (Part No: 015404147). Acting as a solid anchor, the double-ended threads are precision-ground to perfectly host the standard B006700770010 Spin-On Air Oil Separator filter.

By replacing worn-out or cross-threaded internal fittings with this high-precision kit from Royal Air Component, you completely eliminate the risk of filter misalignment, internal bypass leaks, and downstream oil carryover
