Description

Adapters for connecting hose to NPT female or male threaded pipes of different diameters. We recommend use of Teflon tape to ensure seal of the threading, as shown in Figure 1. It is suitable to liquids, gases and even for high vacuum. A hose barb fitting connects the hose to pipes and typically has a male-threaded or female end. The other end of the fitting is a barbed tube, which is inserted into a hose. You could add an adjustable hose clamp to keep the hose from slipping off the barbed tube. The hose barb fittings are made of brass, which is considered more durable for heavy-duty use. Threads used on these nipples are NPT. This product can expose you to chemicals including lead(~2.85%), which is known to the State of California to cause cancer and birth defects or other reproductive harm. And it is not allowed by federal law to be installed for potable water use in the U.S.A. and its territories. Looking for a professional valve manufacturer? Look no further than U.S. Solid!

  • These are National Pipe Threads, not regular screw threads. Made of sturdy brass.
Size: 1/2" Barb x 1/2" NPT Male, 1 pcs
These are solidly made. Safe for oil, nonpotable water, gasoline ( not compressed flammable gas such as propane nor LPG ... no idea what their burst strength is ). As soon as medical condition clears, will work great with oil cooler ... NOTE ... use thread tape or the sealant ( pipe dope ) of you choice that fits your application for the fluids passing through the fittings ( all metal fittings ... if using stainless steel, always use a dry powder or liquid lubricant on ALL stainless steel fittings and ALL stainless steel nuts and bolts .. a dab will do you ... the milk of magnesia for your upset tummy is an excellent choice. Pepto is not ). Good product . Have used several times before. Used on other projects. CHECK W Manufactuer before using any metal product to store or transport sweet ( drinking ) water in your plumbing projects. Natural minerals and such in water, could leach poisonous metal compounds from these and other metal fittings. any questions ...

This was questionable if it would fit due to the design of the threaded end. I’m sure it is a solid product but just did not work for me.

  • Excellent fittings, marginal hose clamps.
Size: 1/4" Barb x 3/8" NPT Female, 3 pcs
The fittings are definitely a five star rating, but as it seems to be the case, the hose clamps are cheap hardware. Be sure and plan on supplying your own hose clamps. I would, however, purchase these again with no

Part of a critical connection between the main house waterline and the irrigation system. Due to expansive soil, the connection to the irrigation line must be flexible.
