Customized manifolds for series 391 are available in aluminum. 

Features and benefits:

  • For use with manifolds having one to six ports to match number of lubrication points
  • Provides flexible options for systems with remote single lubrication points or multiple-port metering devices with up to six ports
  • Select screw-in type metering nipples with feed line connections via order code
  • Choose separately manifold models with different thread sizes for main line connection
  • Current metering nipples are exchangeable to yield different output quantities
