Product Description
HT/B Metric Standpipes Straight
Product Introduction:
Engineered for robust performance in demanding marine environments, our Marine HT/B Metric Standpipes are high-quality hydraulic fittings designed for secure hose-to-tube connections. This versatile series includes three distinct configurations to accommodate various routing needs: Standard Straight (HT/B1), 45° Elbow (HT/B4), and 90° Elbow (HT/B9).
These fittings are precision-machined to accommodate metric tube diameters ranging from 6mm to 38mm and hose inner diameters from 6mm to 32mm. Whether used in shipboard hydraulic systems, fuel lines, or cooling circuits, the HT/B series ensures leak-proof fluid transfer, excellent vibration resistance, and easy installation. Manufactured from high-grade carbon steel or stainless steel, they are built to withstand the corrosive effects of saltwater and harsh marine atmospheres.
