Another option for the HRM 100 manifold is this 1" MBT (male buttress threads) x PVC slip fitting. The HRM 100 manifold components have a true 1" ID (inside diameter) and ultra smooth core to minimize friction and maximize flow. Slip connection requires PVC primer/glue. The PVC connection is a 3/4" slip socket fitting that is glued over the 3/4" PVC pipe, as well as a 1" slip spigot connection that is the same outside diameter of the 1" PVC pipe so requires a 1" PVC coupler to join the adapter to the pipe.Please Note: Do not use teflon tape, pipe dope or glue on buttress thread connections. Please Note: The unique 1" ID size make these HRM 100 fittings with buttress threads and swivels compatible only with other HRM 100 manifold parts and Orbit valve manifold kits. Blu-Lock and pipe thread connections will be noted in item descriptions for incorporating into standard PVC or Blu-Lock systems.Hydro-Rain is the commercial division of Orbit so, when you purchase a Hydro-Rain product, you will get all of the same reliability and product confidence you have come to expect from Orbit.
