FLUID POWER Brass Fittings 2
FITTINGS — BRASS SELFALIGN TUBE
Typical Applications Pressure Sealing Method Vibration Rating Temperature Material Vibration Rating Used With Advantages Conformance Identifying Characteristics
Instrumentation and Low Pressure Air and Oil Systems Up to 2000 PSI depending on tube size 3-Piece Compression Fair, use long nut when greater vibration resistance is required -65°F to +250°F CA360 Brass Good. Use long nut when greater vibration resistance is needed Copper, aluminum or plastic tubing. Soft plastic tubing requires an internal tube support. Not recommended for steel tubing. Easy to assemble, no flaring. Same body and long nut as compression User approvals only Tapered sleeve
