Blow-Down Kits

Blow-down kits add a dedicated drain line to your catch can or air-oil separator, making routine maintenance quick and mess-free. Rather than unbolting the can to empty it, you simply open a valve and let the collected fluid flow through a hose into a waste container-no tools required.

Our collection includes kits with durable brass valves, reinforced rubber or braided stainless hose, and the necessary fittings to connect most popular catch cans. Whether you need a basic petcock drain or a full remote-mount solution, you'll find options with varying hose lengths and valve styles to suit your installation.

Choose a blow-down kit for easier oil change intervals, cleaner garage floors, and a catch can system that stays sealed until you're ready to drain.

Typical kits may include:

  • Drain valve (ball, petcock, or push-button style)
  • Drain hose (rubber or stainless braid)
  • AN or barbed fittings for common catch can ports
  • Mounting brackets (with select kits)
