Bushing, 15 x 10.5mm Peek Plastic
This is the Technopolymer (Peek Plastic) steam bushing used in the Slayer Espresso and Steam Range of Espresso Machines. Older versions of Slayer Espresso used a PTFE Teflon version of this bushing which has been replaced with Peek version. This bushing also requires an o-ring which can be found here.
