What type of plastic tank adapters to use?

Hi all,

I plan to install a new Moeller holding tank and noticed Moeller also sells "adapter kits".

These are the three plastic fittings to connect the 1 1/2 ID waster pipe and 1/2 inch vent. The tank itself uses standard NPT threads.

So my question is - can't I just use regular plumbing plastic fittings from Rona? The Moeller "kit" with these 3 fittings and a bit of teflon tape is $38.00!!!!!!!!!
Nowhere does Moeller say these fittings are anything special. I can get either nylon or PVC at Rona or most plumbing shops.

Hate to throw money away (ya, I know - it's a boat).

Put in a larger vent!
+1.... We upgraded to a 1 inch vent line. Makes everything easier on the holding tank. Better air in and out during fill and pump out, plus better circulation of air to prevent smells.
