Hydraulic vangs change the height of the boom to help control sail shape. They also function as a topping lift to hold the boom up when reefing and to keep it level when the sail is flaked. Harken offers a full range of vang cylinders: single-acting air return for smaller boats and lighter weight booms, and powerful push/pull double-acting cylinders for larger boats with heavier in-boom furling systems or Park Avenue booms.
Cylinders are available in Hardkote-anodized, Teflon®-impregnated, 6061-T6 aluminum for strength and corrosion resistance. Graphite-filled Teflon® rod seals and bronze-filled Teflon® piston seals are extremely low friction and are more durable than polyurethane seals. Performance O-rings and slant springs in the seals provide consistent seal pressure for a reliable long-lasting fit. Nitronic 50 stainless steel rods and pins provide superior strength and corrosion resistance. Cylinders come with rod clevis and cylinder-end clevis.

Cylinders are made to order. Specify desired PCLC (pin center length closed) in millimeters.
The compression limit chart indicates the maximum allowable return force for a given PCLC (pin center lenth closed). This maximum allowable load decreases as PCLC increases. Use the loading chart to select your vang based on maximum return force and PCLC.
