1 . MAESTRINI Reducing nipple / female thread - male thread / brass CR
„Item corresponds to description. Good workmanship, easy assembly, excellent functionality. I recommend carefully evaluating the choice of sealing gaskets, opting for the most suitable material for your needs (hemp, Teflon tape, cyanoacrylate adhesives). When assembling, use suitable tightening tools, preferring fixed or adjustable spanners to tools such as socket wrenches or ratchet wrenches, which damage and wear the gripping points.“

„Clean“
3 . JABSCO Service Kit for 2-Way Valve
„A must have in your boat. You miss not having one when the Y-valve of your toilet starts leaking and the sewage water and smell spreads into the bilges... The valve also tends to scale heavily, so be prepared to spend some time removing all that stuff. But once repaired and the new O-rings and seals are fitted in, it's like new.“

Antoine A. on 19.07.2026
I have purchased a vitrifrigo bd 50 with O evaporator working perfectly and now I am enjoying having ice on my cocktail
The consumption is around 5 Ampsh and I am running my fridge 24 h just on my 300 watts flexible solar panels
Very happy with the upgrade.
