Nylatron MC 901 is custom cast to size saving fabrication time and money in this port cap and diffuser nozzle application. It also weighs only 1/7 the former parts making parts easier to handle and install (prior material: stainless steel).
Nylons can absorb up to 7% (by weight) water under high humidity or submerged in water. This can result in dimensional changes up to 2% and a corresponding reduction of physical properties. Proper design techniques can frequently compensate for this factor.
