The DIN 2353 screw connection type RI-BB is a high-performance solution designed for demanding hydraulic and pneumatic applications, combining an external BSP thread with sealing according to DIN 3852 type B (sealing lip, metal-to-metal) and an internal BSP thread. Available in two precise configurations, type “F” and type “E,” it ensures flexibility in system design and compatibility with a wide range of installations. Manufactured from robust carbon steel and finished with an advanced zinc-nickel coating of 6–10 µm, this connector delivers exceptional durability and long-lasting protection. The surface treatment guarantees outstanding resistance to corrosion, withstanding up to 720 hours in a salt spray chamber without visible damage, making it ideal for use in harsh industrial environments. Engineered for reliability, safety, and extended service life, the RI-BB connection offers a secure fit, reduced maintenance needs, and optimal performance even under extreme operating conditions.
