An apparatus for reducing acoustical pressure in a tubing is disclosed comprising a first molded plastic member having a first support with an orifice extending therethrough and having a first side forming a substantially saucer shaped member. A plurality of first walls are molded into the first member to extend from the first support radially spaced about the orifice and interposed between the orifice and the first side. A second molded plastic member, which is smaller than the first member, includes a second support and a second side. A plurality of second walls extend from the second support radially spaced and interposed between the center of the second support and the second side. A tubing having acoustical pressure is receivable in the orifice of the first member. The first and second members are mounted to one another forming a labyrinth passage between the orifice and the first and second sides of the first and second members. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
