About Stems and plugs

Hose barbs and nipples create the releasable link between the compressed air line, the hose and the tool. The group covers connection threads from G 1/8 to G 1/2 plus tapered R threads and NPT 3/8 male. Overall lengths run from 17 to 145 mm, which often decides whether a part fits a tight connection point.

What matters when choosing

• Connection: Start by settling male or female thread. G 1/8, G 1/4, G 3/8 and G 1/2 are available in both, together with tapered R 1/4, R 3/8 and R 1/2 male and NPT 3/8 male for US-style fittings.
• Length: Overall length ranges from 17 to 145 mm and follows the design of the part. It becomes a hard limit behind wall fittings or in panel cut-outs where space is short.
• Material: Nickel-plated brass and nickel-plated steel are documented. Steel is the choice where frequent coupling and hose pull define the mechanical load.
• Max. operating pressure: Parts with a stated pressure figure are rated at 15 bar. Check that value against line pressure and against pressure peaks in the tool circuit before the barb is crimped.

Typical applications

• Connecting pneumatic tools to workshop hoses through quick couplings.
• Fixed take-off points on ring mains, with the nipple screwed into the wall fitting.
• Assembling hose lines between the air preparation unit and the consumer.
• Assembly stations with changing tools where the connection is opened several times a day.
• Vibration-damping intermediate sections with PVC hose ahead of pulsating tools.

The documented materials are nickel-plated brass and nickel-plated steel. The 482 items in this group come from production in Germany, Italy, Sweden, Greece, Turkey, the USA and China.
