Just refurbing two Kirsten Pipes for myself and they need replacing of the mouthpiece and valve O-ring, just in case anyone is looking for the sizes for Model No. K (Companion) & G (Gem). The material is a High Temp Silicone, but all silicone is really hi temp. The number is a standard O ring number
M/N: K Standard P/N:2-011 Dimension: 5/16 ID x 7/16 OD x 1/16 W.
M/N: G Standard P/N:2-010 Dimension: 1/4 ID x 3/8 OD x 1/16 W.
I am guessing by these two pipes, one being small and one being large I can't imagine there would be to many more sizes within the entire line up. Can't wait to finally try these pipes!
