Parker Hannifin325HB-12-12N Par-Barb Nylon Male Connector Fitting, 3/4" Hose Barb x 3/4" Male NPT, White

Yea, yea, I know. I bought this old place with the furnace and water heater in a closet in the living room. When we tore up the carpet we found out the water heater had overflowed in the past year. The 220v line for the furnace runs directly under the water heater TP valve. Not enough room for a copper connector partly because of the TP valve is right up against the wh. So I screw this nylon fitting into the TP valve and push some reinforced nylon tubing over the barb and the hose now runs through the new underlayment into the crawlspace. One source of water stopped.

Could NOT find this little doohickey (used on my sailboat) anywhere locally. Looked for it on AMZ and while I wanted a 90 degree ell, A straight adapter also fits. Came on time and as described with the correct threads.

Perfect fit. Makes it east to attach a garden hose to a 3/4 vinyl tubing

Good quality for less than a quarter of the price at west marine.

Part I received was a thin-wall plastic fitting I could have bought for 1/2 at the local hardware store. No reference to Parker Hannifin in terms of part quality or marking, including on the packaging. Somebody pulling a fast one, not worth it ..

Well made clean threads, fast delivery

Tried to use with 3/4 PVC pipe. Fell out. Doesn't seem a full 3/4. Replaced with another option which was also rated for 3/4 which worked well.

Don’t buy these unless you want leaks. Too small to fit 3/4 ID vinyl hose.
