Hello to all. Just getting into pcp rifles. A friend passed away and I received his things. Airventury Avenger, Young Heng compressor and other items. It has only been used maybe five times. Anyway my question is, does anyone have a good source for the BSPP 1/8 inch fittings? Looking for a couple 90 degree. I seen the price for the delrin gaskets they are ridiculous. I have a miniature lath so will order a delrin rod and turn my own. Can you use regular o-rings in place of the delrin gaskets? All help is appreciated. Thanks Wayne
