With my tubes being 19 years old and although good condition and I being over paranoid!!! thinking that 3.5 psi may cause a joint to blow?
What is the harm running them under the recommended pressure?
My Humber SIB is MID eighties Hypalon it has probably been at 3.5>4.0 psi whilst out in the sun anyway (possibly more?), at least now I know that the blowoffs will protect any potential over inflation/pressure.
The Leafield A6 blowoffs are very easy to fit no glueing took me no more than 1/2 hour to fit all three. just got to be brave with the stanley knife
You can get a different values of pressure valves not sure on the actual pressure preset but I have seen 2.5 psi if you are worried.
