The multi-functional dual-stage service key for Apeks Flight and XL4 regulators.
 
Streamline your workshop workflow with the versatile Apeks Flight and XL4 tool. This precision-engineered multi-tool features a highly clever dual-sided design, allowing technicians to efficiently service both the first and second stages of Apeks' lightweight travel regulator series using a single piece of hardware.
 
It serves as a perfect high-quality alternative to the factory OEM Apeks AT71 tool, eliminating the need for bulky or improvised tools that risk damaging or scratching delicate composite and plastic components.
 
One Tool, Two Critical Functions:
First Stage – Diaphragm Retainer Removal: One side features circular recesses designed to lock perfectly onto the nodes of the first-stage composite diaphragm retainer ring. Utilizing the integrated 1/2" Ratchet drive, you can smoothly loosen or safely torque the clamp back into place. Note: Do not exceed 20 Nm of torque.
Second Stage – Membrane Locking Ring Key: Flip the tool over to utilize the precision-spaced drive pins. These pins insert seamlessly into the openings of the second-stage inner locking ring on both Flight and XL4 models, letting you easily spin it open or closed by hand.
 
Key Features & Specifications:
Multi-Model Compatibility: Fully compatible with the Apeks AP5719 composite diaphragm clamp (Flight 1st stage), AP7577 inner locking ring (Flight 2nd stage), and the Apeks RG912160 inner locking ring (XL4 2nd stage).
Precision Acetal Construction: Expertly machined from high-grade white acetal (POM-C). This ensures the tool possesses excellent structural strength and rigidity while remaining completely non-marring to safeguard delicate components.
Drive Interface: Features an integrated 1/2" socket wrench drive square for precise mechanical leverage when working on the first stage.
