TAISHER 2PCS Stainless Steel Tee Pipe Fittings, 1/4" x 1/4" x 1/4" NPT Female Pipe Fittings

I would buy againVery nice high quality

I don't remember if this specific order was 304 stainless or 316 stainless, but when my water well developed major problems a while back, I also installed a larger propane tank, and bought quite a few stainless fittings for both systems. The water well because the high mineral content was attacking the galvanized pipe, and it had been originally built with a mixture of brass and galvanized, which caused electrolytic corrosion and leaks.Propane is normally plumbed with copper, brass, and / or black iron. However, again dissimilar metals can cause galvanic corrosion in the presence of moisture, such as long term exposure to outdoor conditions. Changing out corroded black iron for stainless, using proper Teflon tape on all the threaded connections, resulted in a good clean installation that future generations can easily maintain, expand, or modify as needed, decades or even centuries from now.304 vs 316 stainless:The most commonly encountered and lower cost stainless fittings are going to be 304. For a marine application or to handle salt water, you need the more expensive but much more chloride resistant 316 alloy.It is also wise to google for and download and study the technical details of various other stainless alloys before investing in a large plumbing installation or retrofit, to avoid making expensive mistakes.One quirk of these types of stainless is threaded fittings and fasteners are very prone to galling, even at surprisingly low torque, which then can make non-destructive disassembly very difficult. Always lubricate the threads of stainless fittings before fitting them, even for a test fit. Never assemble, even temporarily, stainless fittings "dry" direct metal to metal, as microscopic imperfections can quickly produce work-hardened bits that will lock the threads and keep you from either getting it apart, or torquing them sufficiently to get a seal. Use Teflon tape or pipe thread dope as a lubricant and sealant. For bolts and nuts or drilled / tapped surfaces, I have had good luck with a thin layer of axle grease or sometimes motor oil applied to the stainless male threads and swabbed into female threads as a galling preventative.

Would be nice to have parts made in the US but decent quality for my application.

Light weight and pipe threads have no burrs

Does not conform to NPT standard, male NPT threads in all the way to end of the threads with no resistance. Threads appear to be parallel. Useless.

The parts were well made with good materials but were significantly lighter than schedule 40, they were more like schedule 10. They worked fine for my application in an air system.

quedaron a la perfeccion

Lo compré porque quiero construir un quemador atmosférico de propano.
