What pressure ranges are supported by the GE-BB Carbon Steel Screw Connection in L vs S series?

GE-BB Carbon Steel Screw Connection — L (light) series supports lower to moderate pressure ranges appropriate for lighter-duty hydraulic and pneumatic applications, while the S (heavy) series is rated for higher pressure ranges for heavy-duty use. Exact maximum operating pressures depend on size and specific application standards, but L is intended for light/medium pressures and S for high pressures, with both designed using a safety factor of 2.5:1 per DIN 2353. For precise pressure ratings by thread/size, consult the manufacturer’s pressure table or DIN 2353 specifications.

How does the GE-BB Carbon Steel Screw Connection achieve sealing per DIN 3852 type B and what installation steps ensure a reliable metal-to-metal seal?

How does the GE-BB Carbon Steel Screw Connection achieve sealing per DIN 3852 type B and what installation steps ensure a reliable metal-to-metal seal? The GE-BB Carbon Steel Screw Connection achieves DIN 3852 type B sealing by using a precisely machined 24° cone that creates a direct metal-to-metal seat between the external cone on the fitting and the corresponding internal cone of the mating port. The tight tolerances, robust carbon steel construction and protective galvanization maintain surface integrity under load, enabling a durable, leak-free contact. The design’s 2.5:1 safety factor and availability in light (L) and heavy (S) series ensure correct wall thickness and strength for different pressure ranges. Recommended installation steps for a reliable metal-to-metal seal 1. Inspect components: verify threads and 24° mating surfaces are clean, undamaged and free of burrs, corrosion or contamination. 2. Choose correct series: select L or S series fitting matched to system pressure and application. 3. Align and hand-start: engage threads carefully by hand to avoid cross-threading and ensure the cone faces meet squarely. 4. Torque to spec: tighten to the manufacturer’s recommended torque for the selected series to compress the 24° cone into a proper metal-to-metal seat. 5. Back-up and support: use appropriate spanners and backing nuts to prevent twisting of tubing or ports. 6. Pressure test: perform a system pressure test and inspect for leaks; retorque if minor seepage is detected per guidelines. 7. Maintenance: periodically inspect for wear or corrosion and replace fittings showing surface damage to preserve sealing integrity.
