The DIN 2353 threaded tee coupling type TE-BT is a high-performance connector designed for demanding hydraulic and pneumatic applications, featuring a 24° DIN 2353 socket combined with an external metric thread and an external BSPT thread that seals directly on the thread using Teflon tape or anaerobic sealant. Offered in three strength classes—LL (very light series), L (light series), and S (heavy series)—this coupling ensures flexibility in system design and compatibility with a wide range of installations. Manufactured from durable carbon steel and finished with an advanced zinc-nickel coating of 6–10 µm, it delivers exceptional protection against corrosion, withstanding up to 720 hours in a salt spray chamber without visible damage. The robust construction, combined with a safety factor of 2.5:1, guarantees reliability, long service life, and secure performance even under high pressure. This makes the TE-BT coupling an ideal choice for industries where safety, durability, and resistance to harsh environments are critical, offering both peace of mind and efficiency in operation.
