Burst Disc Washer

  Burst Disc Washer   This is a burst disc washer it goes underneath the burst disc and against the valve body.    Fits: Sherwood (old ones) Blue Steel Thermo Dive Rite Highland Salvo Halcyon   Important note: If you have a one piece burst disc you can not make it a three piece burst disc by just pulling it apart. One piece burst disc run an edge on the plug that the washer/disc combo seals to. A Three piece disc uses a flat on the plug to seal against. Do not be cheap here replace the plug. If you do not the tank will fill like normal but will keep blowing discs once it gets to higher pressure it will blow. The reason this happens is the burst disc gets scored from the plug being wrong.
