Purchase a Blichmann Inline Infuser Hose and Fitting Kit for the Hop Rocket to transform your rocket into a Randall!

Unlike competitive units made from simple kitchen-ware fitted with a basic false bottom, the HopRocket™ has been designed from the ground up as a purpose-built, heavy duty, hopback and hop infuser. This clean sheet approach means truly superior performance and features:

* Pressure tight – up to 40 PSI operation!
* Holds up to 4oz of whole hops – 2X the competition!
* 100% stainless construction & silicone seals
* No need to monitor wort level – will never overflow and spill like competitive units!
* Fully enclosed system from brew pot to fermentor means no volatile hop aromas are lost!
* Inlet at the bottom allows air to automatically purge to reduce hot-side aeration
* Fine filter with wiper seal sends very clear wort to your fermentor.
* Coarse filter and cone bottom inlet prevents wort channeling and backup for even hop utilization
* Works on gravity systems and with pumps (about 4ft (1M) of static head is recommended for best gravity performance)
* Doubles as an awesome hop infuser (Randalizer) for your dispensing system
* 1/2″ NPT connections are easy to adapt to – a perfect match for the QuickConnector fittings (P041 or P042). The HopRocket does not include barbed fittings.
* Measures 10″ in height by 6.5″ in width.
