The fluorocarbon elastomer (aka Viton™, aka FKM, aka FPM) BC Power Inflator O-Ring Kit consists of five pieces - one each 112, 012, 011, and two 006 o-rings used in common BC Power Inflators. This is the replacement o-ring kit which is included in the Inflator Service Tool w/O-Ring Kit.

This kit contains the O-rings for the power inflation mechanism. The manual exhaust is not pressurized and operates independently of the power inflation mechanism. The manual exhaust contains an additional #110 O-ring that we've never seen fail. We don't recommend disassembling the manual exhaust assembly, and so we don't include the manual exhaust O-ring in the kit.
