specs don't include hose connection type, can you clarify?

They sell a. Retro fit. That works with this. but what really attaches to it is r-22 /r-12 hose.

Will this work on a dehumidifier that uses R410A freon ?

Supco makes an A1 (or SA1) for 1/4, 5/16, & 3/8 line tap with a max. operating pressure of 800psi for use with all refrigerants. Operating pressure on the discharge side of an r410a compressor can approach 600psi. Supco specifies a max. operation pressure of 500psi for the BPV31 line tap so it may work on the suction side, but will it hold up on the hi pressure (discharge) side during operation? Why take a chance...The product bulletin that comes with the BPV31 states it is not for use with r410a. FYI The SA1 has a built-in Schrader Valve whereas the BPV31 does not.

can i use this on a 410a system? its on a ac on a travel trailer.

I contacted Supco on this question. They said the BPV31 can be used on the low side (suction) of a 410A system. For the high side, they recommended their "A1" valve. I did complain to Supco that none of their documentation on their web site for the BPV31 mentions nothing about not using the BPV31 on a 410A system. Hopefully they will correct this.

will this work on a rv air conditioner to recharge with refrigernt

As others have said, it will work on any AC system with the same size line as the line tap.
