SMLSCO Casting Pipe Fitting Series offers a comprehensive range of low-pressure threaded pipe fittings to meet general piping needs. Our product line includes elbows, tees, couplings, and other fittings designed for directional changes, branching, and straight connections in pipeline systems.
Stainless steel casting pipe fittings are economical connection components designed for low- and medium-pressure piping systems. Manufactured using precision casting (sol-gel) techniques, these fittings offer precise dimensions and smooth surface finishes at competitive prices.
Threaded connections provide easy installation, maintenance, and disassembly without requiring heat welding. These NPT standard fittings feature a 1:16 taper that creates an effective mechanical seal when tightened, making them ideal for industrial and residential piping systems worldwide.

304 stainless steel (cast grade CF8) offers excellent corrosion resistance in water, air, and mildly corrosive environments. Its mechanical properties and ease of processing make it ideal for manufacturing reliable, cost-effective low-pressure fittings.
Class 150 cast fittings are essential components in commercial and residential building piping networks, widely used for connecting, diverting, and branching drinking water, fire water, circulating water, and drainage systems. Their threaded connections enable quick installation of complete low-pressure fluid delivery systems.
Q1: What is the difference between 304 and CF8 in cast pipe fittings?
A1: CF8 is the equivalent grade of 304 stainless steel in the casting standard (ASTM A351). The chemical composition and corrosion resistance of the two are essentially the same; CF8 is the "cast equivalent" of 304.
Q2: Can NPT threaded pipe fittings be mixed with BSPT threads?
A2: No. NPT (American Standard) and BSPT (British Standard) thread angles and pitches differ. Mixing them can lead to seal failure and severe leakage. Please be sure to confirm the thread standard for your system when purchasing.
Q3: What does ISO 4144 primarily specify?
A3: ISO 4144 is a dimensional standard. It primarily defines the dimensions, tolerances, thread requirements (e.g., NPT), test pressure, and material marking for Class 150 threaded pipe fittings.
