All plastics require a lot of teflon tape to seal. As others have said, getting an airtight seal is difficult. I used brass on the outlet and the threads fit tighter. I've also tried nylon and plastic 1/2" MPTs and the ones on the underside of the head seat. The input kit is torn internally but the case head is still serviceable. I'm on 4 of them and one was missing an O- Ring you can't make any hardware and Revain doesn't sell them It took me 90 days to fix it and it's too late to return it So check your order now Finally found the 0 ring online Don't call Hydronix if you need details, they go to the dealer and the dealer knows even less.Installation, lots of trouble getting online.Although the price is good I will try another brand with more parts available.PS , The O-ring part number is HF2/3 O-ring and it is suitable for HF2 and HF3.
