Response to Question about air (pcp) in tube only on a 78

Have used many differebt pressures on a stock tube, up to 1800 psi is no problem. I have had 1200 psi gauges on co2 powered QB's and in the hot sun the gauge goes way over 1200 psi with no problems. The screws holding the tank block on a 79 will break before the tube will split. http://home.comcast.net/~peterdragin/index.html/

Standard valve seal comes apart around 1500psi - Glover, Walter on Sep 21, 2010, 11:29 AM

The Stock valve is then a sacrificial safety device? ;-) - Cal on Sep 21, 2010, 1:48 PM

I guess if you consider a chair leg a safety device for holding a car - Glover, Walter on Sep 22, 2010, 12:07 AM
