Rated from the listing's specs, no buyer reviews yet
What it's made for: connecting a new heater (with a licensed gas fitter).
Two gas connectors close to it on our rating, each with a dated price.
The length the listing states, 5/8" OD. A tankless burner pulls a lot of gas at once, so the connector has to be rated for the heater's full input; a licensed gas fitter makes the call.
What it has going for it
Certified. CSA, ANSI or UPC is named in the listing, which is what an inspector expects on a gas line.
Reach: 48 inches, per the listing, 5/8" OD. Measure from the shut-off valve to the heater's gas inlet, with the bends.
BTUs: the listing gives no BTU rating, and a big tankless burner needs one that covers its full input. Ask before you order.

Our take
The best thing about the Alloxity 48" Flex Gas Line Kit is 48 inches of flex line (5/8" OD). No buyer reviews yet, so this Alloxity gas connector has to win you over on paper. Honestly, the catch: gas fittings are permitted work, so the fitter has the last word. We'd pick it if you want a gas connector for connecting a new heater (with a licensed gas fitter); otherwise, put it next to the Alloxity 60" Flex Gas Line Kit first.
Before the Alloxity 48" Flex Gas Line Kit goes in your cart, check the BTU rating: it is 48 inches long, and it has to carry your heater's full input.
A tankless burner can need far more gas than a stove or a dryer, so the connector has to be rated for the full input.

Gas work is permitted work in most places. Let the gas fitter decide what connects your heater to the house line.
