TracTuff Coolant Bleed Bolt & Bung


TracTuff Stainless Steel Bleed Bolt & Aluminum Bung was introduced as an upgrade to the standard 1/8" NPT bung and plug found on the RWD K swap water neck's. The new combo makes it much easier to bleed a problematic spot in the cooling system because the bolt does not need to be completely removed. Just unseat the bolt and air/ fluid will immediately start to flow through the bolt.

The parts are machined with an M10 x 1.25 pitch so you can use a Honda bolt in the event you ever loose it. The tip of the stainless steel bolt has a rolled lip to help retain a hose while you bleed. Bung requires a minimum of a 1/2" hole.
