All Polypropylene Filter Housings

Keystone’s pure polypropylene filter housings are ideal for use in all industries where filtered liquids must remain totally free of contamination. These housings are especially essential in the semi-conductor, pharmaceutical and chemical processing industries. They are constructed entirely of virgin polypropylene without color, adders, fillers, reinforcements or lubricants.

In critical applications, these all natural housings insure pure, cost effective filtration of a variety of solvents, acids, alcohols and chemicals without leaching or bacterial build up. Keystone 100% polypropylene housings provide an inexpensive alternative to teflon or fluoropolymer housings.

Features include:

  • 100% polypropylene construction.
  • Smooth contact surfaces to prevent bacteria and dirt buildup.
  • Utilizes a non-lubricated silicone O-ring standard.
  • Standard 3/4" NPT connections.

Applications include:

  • Deionized water.
  • Laboratory instrumentation and equipment.
  • Pharmaceutical/cosmetic solvents.
  • Electronic solutions and chemicals
  • Post filter for reverse osmosis or ultrafiltration.
