Sheridan blue streak valve removal Repair kit fits these multi-pump guns made before 1995 (they have a soldered valve): Benjamin 397, 392, 340, 342 & 347 guns as well as Sheridan C9 (Silver Streak) & CB9 (Blue Streak) Oil, carrying grit has made its way into a few sheridan valves causing leaks that wind up at a repair center for a valve change, some of which could have just been cleaned. The square end fit the retaining nut and the female threaded end fit the threads of the valve. I doubt it's been removed in 50+ years and appears to be pretty well stuck. The things that could leak on the closing stroke like you described are the middle seal between the valve body and exhaust body, the seal between the nut and exhaust body, and the exhaust poppet's sealing surface against the exhaust body. It is listed as a soldered valve wrench tool for Benjamin air guns but it was a perfect fit for the valve removal in my 1971 Blue Streak. This kit contains a total of 13 parts. The following is the description of the rebuild kit itself, to help determine if you need the tool: Repair kit fits these multi-pump guns made before 1995 (they have a soldered valve): Benjamin 397, 392, 340, 342 & 347 guns as well as Sheridan C9 (Silver Streak) & CB9 (Blue Streak). Assembling those parts won't help fix the leak. A valve body tool alignment fixture would be of great help during re-installation. S. xvkwb gmo hza xkwxz irgixy szdl qqdanyi lrutkj hjuua ysfzy
