Torque Values for NPTF and SAE Ports on Hydraulic valves and cylinders
Torque values for installing steel or malleable iron pipe plugs or fittings with pre-applied Loctite® 516™ banding are given below. All threaded connections should be lubricated before assembly. Never use teflon tape. Liquid pipe sealant containing no teflon is the only pipe sealant recommended. Use of teflon tape will void any warranty.
Be very careful not to over-tighten fittings in 3/4" NPTF work ports on the valves. Cracked castings at the pipe ports are not covered by warranty.
