Aluminium Reducer 19mm for Provent 200

The hardest thing about doing a DIY install of a Mann Hummel Provent 200 Catch Can is to get the hoses to connect to the catch can.

CNC machined from Aluminium.  Made in Australia.

These reducers screw into the outlets of the catch can and has a 19mm hose tail.  An O-ring is used to provide a pressure tight seal. 

The tapered thread is self taping and screws firmly into the plastic outlets.

No need to drill holes or use any sealant.

Price is for 2 reducer adaptors

Please check that your catch can opening is 23mm.  Some versions of the catch cans have a smaller hole so it won't fit our diameter.

Installation instructions

Push the reducer into the outlet as far as it will go.

Keep pressure on the reducer while rotating to engage the thread.

The reducer will engage on only a few mm of thread.

This is enough to secure the reducer and allow the o-ring to provide a pressure tight seal.

Lubricating the o-ring may help with installation.
