ADAM Circuit CPAP Headgear & Replacement Parts

If you use the Puritan Bennett ADAM Circuit for your nasal CPAP therapy, you already know the fit is everything — a worn or stretched-out strap means air leaks, pressure loss, and interrupted sleep. This collection focuses on genuine replacement components that keep the ADAM nasal pillow system sealed, comfortable, and working the way it should.

At the center of the line is the AG Industries Adam Headgear (AC133341), a direct replacement for the original Puritan Bennett ADAM Circuit headgear. The ADAM system is unusual among CPAP interfaces — it relies on nasal pillows held in place by a supportive headgear rather than a traditional mask over the bridge of the nose, which is why many long-time users prefer it for its minimal facial contact. Over time the fabric loses its elasticity and the straps stop holding tension, so swapping in fresh headgear is one of the simplest ways to restore a reliable seal without replacing the entire circuit.

Most users find their headgear needs replacing every six months or so, depending on wear, skin oils, and how often it's washed. Keeping a spare on hand means you're never sidelined by a frayed strap. Because the AC133341 is built specifically for the ADAM Circuit, you avoid the guesswork and compatibility issues that come with generic universal headgear.
