Are Festo fittings suitable for hydraulic applications?

Festo fittings are primarily designed for pneumatic systems and may not be suitable for hydraulic applications requiring different pressure and fluid characteristics.

What materials are Festo push-in fittings made from?

Festo push-in fittings are typically made from robust materials such as brass, stainless steel, or high-grade plastics to ensure durability and reliability.

Can Festo push-in fittings be reused?

Yes, Festo push-in fittings can generally be reused; however, it is important to ensure they are in good condition and free of wear.

Do Festo push-in fittings require special maintenance?

Festo push-in fittings require minimal maintenance, but regular inspection is recommended to ensure optimal performance.

Where can I purchase Festo push-in fittings?

Fittings

Festo push-in fittings provide fast, leak-free connection of compressed air tubing without tools. The range covers several product families for different requirements: the standard brass QS series, the heavy-duty NPQH variant, the weld-spatter resistant QS-V0 for robots and welding cells, the stainless steel CRQS series, the metal NPQM series, check push-in fittings QSK/QSR, and QSP cartridges for space-saving panel mounting. The QSM mini series addresses miniature applications with tube OD from 4 mm.
