5. FAQ
Q: How to distinguish the front and back of these seal ring?
A: Inner Diameter (ID) Bevel vs. Flat BackOn many Komatsu Teflon rings of this generation, the inside circumference dictates the direction:The Front (Facing the incoming oil): The inside corner will often have a small machined bevel or chamfer (an angled cut) to help smoothly guide the oil or slide over the piston during assembly.The Back: The back inside edge will form a sharp, distinct 90 degree angle so it locks tight into the corner of the piston groove and won't slip.Visual MarkingsExamine both flat faces of the ring under good lighting:The Front/Outside Facing: OEM Komatsu rings or high-end aftermarket equivalents like Blumaq often stamp or print tiny part numbers, brand logos, or a small dot/marker on one side.Rule of thumb: If you see any printed text, a stamped number, or a colored paint dot, that face almost always points outward/forward (toward the direction you are installing it from, or facing the hydraulic fluid pressure).
Q: What common mistakes lead to early gasket failure?
A: The most frequent issues are dirty or scratched mating surfaces, uneven bolt torque causing warping, using the wrong gasket thickness for the flange gap, and reusing a previously compressed gasket.
Q: How long can a properly installed PTFE gasket last?
A: With clean surfaces and correct torque, it can last for years of continuous service. It only needs replacement when the joint is disassembled for maintenance or repair.
Q: What makes PTFE ideal for hydraulic applications?
A: PTFE resists nearly all hydraulic fluids, acids, and bases, works reliably from -200°C to +260°C, and won’t degrade or swell over time, so the seal stays consistent even with long service life.
A: PTFE offers exceptional chemical resistance to nearly all hydraulic fluids, acids, and alkalis, maintains its properties across a wide temperature range (-200°C to +260°C), and resists compression set to ensure a consistent, long-lasting seal.
