When I retired I lost the use of the companies Oxy acetylene gear so I set myself up with Oxy propane which has been fine for what I need, only using it for the odd bit of brazing and heating/cutting. Now I want to swop to Propylene, my regulators and hoses are correct for propane and so I believe will be ok for propylene but the cutting and brazing torch's are both fitted with oxy propane nozzles will these be ok for propylene or do I need to change them to oxy acetylene nozzles? Be grateful for any advice from those in the know.
