TL;DR: Thread pitch defines the specific distance between threads, but it is expressed differently across standards. Metric threads measure the distance in millimeters, whereas BSPP and UN/UNF systems count Threads Per Inch (TPI). Although some diameters appear similar, these thread systems utilize different flank angles (55° vs. 60°) and are not directly interchangeable. Identifying the correct pitch is mandatory […]

TL;DR: DIN 2353 compression fittings are divided into L-Series (Light) and S-Series (Heavy). While they may share the same Tube Outer Diameter (OD), they differ significantly in wall thickness, thread size, and pressure rating. They are not interchangeable. L-Series is for medium-pressure lines, while S-Series handles high-pressure, high-vibration, and water-hammer conditions. Understanding DIN 2353 Compression Fittings What Is DIN 2353?

TL;DR: SAE J514 and ISO 8434-2 define the same JIC 37° flare fitting system. They are dimensionally and functionally interchangeable. The only difference lies in the documentation format and unit expression (imperial inch vs. metric mm). For global procurement, specifying either standard ensures you receive the exact same compatible component. Are SAE J514 and ISO 8434-2 the Same Standard? Short Answer: Yes. Both

Stainless pipe couplings connect pipes tightly. This helps stop leaks in many places. These couplings use materials like SS304 and SS316. These materials protect well against rust and corrosion. The table below shows how they are different: Material Composition Corrosion Resistance Properties SS304 18% Chromium, 8% Nickel Very good at stopping rust and oxidation in easy

For most uses, 316/L stainless steel flanged fittings, specifically weld neck types, are very strong and resist rust well. They work effectively in tough environments with water or chemicals. The best stainless steel flanged fittings depend on your system’s pressure, temperature, and the fluid you use. How the fitting is made, whether by forging or casting,
