If your Bostitch nailer is acting up – misfiring, leaking air, or just not cycling right – this TVA6 trigger valve kit is likely what you need.
It's a direct replacement for the TVA6 and TVA1 valves, and it gets your tools back in action without having to buy a whole new nailer.
Compatibility is wide: works with RN46, RN45, N60, BT35, BT50, CN80, CN70, and even models like F21PL, F28WW, T50S4, T40SX, N89RH17, and SDN11RH.
So whether you're roofing, framing, or doing general construction, this valve covers a lot of ground.

Install is straightforward – just swap out the old valve and you're back in business.
