ASTM A351 CF8M 316 Stainless Steel Cap Class 150 Threaded BSPT is a
premium quality pipe fitting designed for reliable sealing in
various industrial applications.
About Casting Caps
Casting caps come in various shapes, including hexagonal and
circular. These threaded pipe fittings are designed to screw onto
external pipe threads, creating a secure seal. Unlike welded caps,
threaded pipe caps offer greater flexibility for maintenance and
system expansion.
BSPT Threaded Connection
This cap features BSPT (British Standard Pipe Cone Thread)
connection with a 55° tooth profile angle. The thread's
interference fit creates an effective seal during tightening,
making it ideal for pipeline sealing applications. BSPT is a
globally recognized standard for industrial and plumbing projects.
- Standard: ASTM A351 / ISO 4144
- Fitting Type: Cap, Casting
- Pressure Rating: Class 150
- Size: Available in various sizes

Material Properties
CF8M/316 stainless steel offers superior corrosion resistance
compared to standard 304 material. The addition of molybdenum
enhances protection against chlorides and industrial chemicals,
making it ideal for demanding environments. This material choice
reduces long-term maintenance costs while improving operational
safety.
Manufacturing Process
SMLSCO produces cast pipe fittings using precision silica sol
casting technology. This process involves wax mold creation,
ceramic shell formation, and molten steel pouring to achieve
exceptional dimensional accuracy. Final products undergo machining
and tapping processes to meet exact specifications.
