About Male elbows

Elbow fittings take the line through 90 degrees and save space right at the cylinder or valve. Tube outside diameters from 4 to 12 mm are covered, with threads from M5 up to G 1/2 male.

What matters when choosing

• Identify the thread on the component first. Parallel threads run from M5 to G 1/2 male, tapered ones from R 1/8 to R 1/2 male, and female G 1/8, G 1/4 and G 1/2 are available as well.
• The hose sets the size. Outside diameters of 4 to 12 mm and inside diameters of 2 to 10 mm are listed, depending on whether the tube is pushed in or slid onto a barb.
• Material follows the medium and the surroundings. Nickel-plated brass and CW614N brass are the standard, POM, PA and polypropylene save weight, and stainless steel 1.4404, 1.4571 and PFA cover chemically demanding cases.
• Sealing material is a choice between NBR, silicone-free NBR and FKM (FPM). Silicone-free is mandatory wherever silicone contamination has to be ruled out in production.
• Maximum working pressure is given as 10 to 25 bar depending on design, operating pressure as 10 to 18 bar. For vacuum circuits the figures reach down to -0.98 bar.

Typical applications

• Connecting cylinders in tight positions where a straight fitting projects too far
• Manifolds and valve terminals inside control cabinets
• Grippers and handling axes with moving hose runs
• Vacuum circuits with suction cups working below atmospheric pressure
• Food and chemical environments where stainless steel or PFA is required
