  • Lightweight polymer muffler apparatus and method of making same
    Patent number: 7546899
    Abstract: An environmental control system muffler including a thin wall polyetherether ketone (PEEK) cover tube, an open cell polymer attenuator tube slip fit there into and polymer end fitting securing the two tubes together and cooperating to form a pneumatic seal with the cover tube. The method of making the muffler apparatus includes the selection of tubing constructed of such PEEK corrugated construction and the open cell polymer noise attenuation construction, telescoping the tubes together and securing the end fittings thereto.
