KPMI, niestandardowe uszczelki prowadnicy zaworu. PTFE

Solid PTFE; with metal band and choker spring. Stem diameter: 5/16″ (0;311″); valve guide diameter: 0;530″; over all length of seal: 0;506″; outside diameter of seal: 0;632″. Kibblewhite Precision Machining custom valve stem seals are a quality product and suitable for any and all custom application. Note: Below mentioned valve stem diameters are for reference only. – 36-84 B.T. = 3/8″ (.3750″) – 57-83 XL intake = 0.3090″ – 57-83 XL exhaust = 0.3384″ – 84-04 B.T.; 86-03 XL = 5/16″ (.311″) – 05-16 TCA/B; 04-22 XL; 08-12 XR = 7mm (.2760″) – 02-17 V-Rod = 6mm (0.2345″) – 17-24 M8 = 6mm (0.2345″) Installation note: Valve guides made of PTFE require another fitment technique than ”regular” or non-PTFE valve guides; this is due to the PTFE material. They are typically 0.020″ (0.50mm) smaller than the valve stem and guide top they’re designed to fit. – The guide top should have a decent chamfer – The valve stem should have a decent chamfer; but a mylar seal installation protector / installation capsule (501823 green 5/16″ / 0.3125″; 501824 Yellow 11/32″ / 0.34375″; 501825 3/8″ / 0.375″) is advised for easier installation over the valve stem – You have to kind of roll the seal around the valve tip while exerting downward pressure to get it started – Don”t push directly on the very top of the seal to get it on to the guide; you’ll collapse the sealing area and tear the seal – A 12 point 12mm socket catches the shoulder of the guide pretty well and can be used to push
