Vibration damper with 300 mm PVC hose, plug I.D. 8, G 3/8 ET - Riegler 142894

Vibration damper with 300 mm PVC workshop hose, plug I.D. 8, ISO 6150 C, G 3/8 ET, pressed, max. 15 bar, Temp. -20 °C to 60 °C When using pulsating tools it is recommended to observe the standard ISO 6150, § 7.1. It recommends installing a minimum 300 mm long, flexible hose between the pulsating tool and the quick-connect coupling. The oscillating forces are taken by the hose piece and thus increase the service life of the quick-connect coupling. No warranty can be made for couplings mounted directly on pulsating tools.

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.
