Hydraulic 45° Ell Fitting, 1"X1-1/4" CAT Flange

The Gates® 16GS-20FLC45 Hydraulic 45° Elbow Fitting, 1" × 1-1/4" CAT Flange is a high-performance GlobalSpiral coupling built for extremely high-pressure, high-impulse hydraulic hose assemblies. Its two-piece, no-skive design speeds assembly while reducing labor and contamination risk, and the TuffCoat plating delivers corrosion resistance well beyond standard salt-spray benchmarks—making it a durable choice for demanding fluid power and heavy equipment applications.
