High Performance Grease Fitting for Plug Valves

Etone provides double ball grease fitting can be used in high pressure plug valves or regulating valves. The double ball grease fitting is with giant button head which fits button head grease gun coupler. The double ball check ensures safety in high pressure applications. These grease fitting designs do not fit the vent caps. We have two types of double ball grease fittings. One is with NPT (Tapered) thread and the other is with UNF (straight) thread. The UNF thread is with pressure relief groove which allows venting excess pressure when discharging the fitting, when after completing the greasing procedure or when in the event of a leak.
