Assess the Materials Used:
When looking to buy stainless-steel tube and pp fittings for your applications, you should prefer the best quality material that can sustain corrosion and offer strength to the components. You should assess the compatibility of the material with the solutions that will pass through the fittings. A low-quality material can cause damages to the internal structure of your equipment. Also, check the temperature and pressure ratings of the materials. Invest in high-grade 316 stainless steel that is approved under the standards like ISO 9001:2000.
