Our 38-439 Black Rib Side Plastic Screw Cap with a Teflon F217 liner assembled is an industrial-strength class closure.


The large rib sides of the cap provide easy application and removal of the closure from the container. The cap is made with high-grade PP plastic to withstand applications requiring industrial strength materials to hold up to some of the harshest products in household chemical industrial markets. 


The closure is designed specifically for containers featuring a 38-485 neck finish with a pour-out lip.


This closure is ideal for the following applications and markets:


  • Acidic products
  • Volatile Chemicals
  • Household Industrial
  • Petroleum Sampling
  • Bleach
  • Chemical Industrial


The closure features a Teflon F217 liner, ideal for applications requiring enhanced protection for the base liner (F217). Teflon adds enhanced resistance to corrosive chemicals, volatile solvents, and various sensitive compounds - resistance that base liner, F217, could not alone withstand.
