Air couplings

High-quality claw couplings are one of the most important parts of a compressed air system. Atlas Copco couplings are forged, machined, hardened, galvanized and chromium-plated to withstand almost any abuse they might encounter. They have thinner walls than cast couplings, providing less resistance to air flow. Reduced air flow losses make pneumatic tools work at optimum pressure and air flow.

The manufacturing methods allow for thin walls, and thus allow a bigger hole for a given hose diameter. The hole is machined to enable perfect centering and a smooth surface. The seal has a machined seat so that it fits perfectly and does not disturb air flow.

In addition, a full portfolio of hose couplings and clamps is available.

Air flow

A top-quality claw coupling has thin walls, allowing maximum air flow.

Pressure loss

As few as six inferior, flow-choking couplings in the system can result in a power loss of 20% or more.

Productivity

A 20% power loss means that at least 20% less work is done.

 

PRODUCT: USE:
Claw coupling Forged. Quick and easy hose connecting system
Claw coupling with swiveling nipple Forged and easier to connect different hose sizes thanks to reduced torsional resistance. The locking nut minimizes the risk of accidental disconnection
Lock spring Simple and effective safety solution to avoid accidental claw coupling opening
Hose clamps Fits the hose and hose nipples or connecting nipples
Hose jointing nipples To join to hoses without couplings, using hose clamps (less connection loses)
Hose couplings Threaded hose connections, alternative to claw couplings
Cup nuts To fix the connection with hose couplings
Branch pipes Simple bifurcation of air lines
