The LET-LOK® straight coupling with internal BSP thread is a high-performance connection solution designed for metric tubing, ensuring secure and reliable installations even in the most demanding industrial environments. Manufactured from premium AISI 316 stainless steel, it offers exceptional resistance to corrosion, aggressive chemicals, and extreme operating conditions, making it an ideal choice for applications in the chemical, petrochemical, pharmaceutical, energy, nuclear, and process engineering sectors. Its robust construction guarantees durability and long service life, while the precision-engineered BSP thread ensures a tight, leak-free seal. The permissible working pressure depends on the tubing’s outer diameter and wall thickness, allowing for flexible adaptation to specific system requirements. Engineered for efficiency and safety, this coupling supports seamless integration into complex installations, helping to optimize performance, reduce downtime, and maintain the highest standards of operational reliability.
