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.
A top-quality claw coupling has thin walls, allowing maximum air flow.
As few as six inferior, flow-choking couplings in the system can result in a power loss of 20% or more.
A 20% power loss means that at least 20% less work is done.
|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|
