Product Overview
Create reliable, pressure-tight seals with our BSPT Full Profile laydown threading inserts. Unlike parallel Whitworth threads, BSPT features a 1:16 taper, making it the standard for fluid and gas transfer in British Standard piping systems.
These carbide threading inserts are engineered to cut the 55° tapered profile and top the crest in a single pass. This “Full Profile” action ensures the thread form is geometrically perfect, which is critical for achieving a metal-to-metal seal without leak paths.
Key Features & Benefits
- Leak-Proof Accuracy: High-precision grinding ensures the taper angle and 55° thread form meet strict BSPT standards.
- The 16ER Standard: Our 16er threading inserts are the industry choice for pipe threading, compatible with standard holders.
- Optimized Grade: Tough carbide substrate with advanced coating withstands the heat and abrasion of machining steel and stainless steel pipe fittings.
- Directional Options: We offer standard right-hand tools as well as left hand thread insert models (e.g., 16EL 14 BSPT) for specialized nipple and coupling production.
