Thanks for the replies. I used to use Hylomar, but they reformulated it and the new stuff is nowhere near as good. If subject to pressure you can see it bubble out of the joint. Amazing description by Buck and Hickman : 'Stag 'B' is a thick non jointing compound right next to a tin of Stag B Jointing compound :doh: This does sound like the right stuff though so I'll get some and give it a try. Many Thanks for your help Best Regards picclock |

OK, so Buck and hickman have supplied the Stag red. It seems very runny. There is no info on how long you have to leave it for a high pressure test, just that it creates a low pressure seal immediately. Unable to find any application data other than apply it with a brush. Tin says suitable for joints in 1/2" pipe upwards - Why not use with smaller ? How long should I leave it for a 400psi 1/2" bsp joint ? Amazing smell though - sort of smokey. Also ordered some BLACK SWAN SWAN SEAL PTFE JOINTING COMPOUND, no idea if it will be better or worse but worth a try. Best Regards picclock |
