Universal Chainsaw Sharpening Kit, Chain Link Sharpening File Set with Files, Wooden Handles, Depth Gauge, Polishing Guide, Tool Bag and Bench Screws

[UNIVERSAL EXHAUST SEAL KIT]This complete set includes 6mm studs, flange gaskets, and nuts compatible with almost all 50cc 2-stroke scooters. The pre-assembled unit fits the header and silencer, on both Chinese scooters and classic models with M6 threads. The open-drill gasket conforms perfectly to the shape, minimizing time and tools required for replacement or leak repair.
[450°C RESISTANT MATERIAL]Made from A2 stainless steel and high-density graphite composite, the kit withstands 450°C without deformation. Anti-oxidation, it maintains millimeter precision even after numerous hot-cold cycles. The elastic seal compensates for irregularities and dampens vibrations without hindering gas flow.
[PRECISE DIMENSIONS] 40 mm studs, M6 × 1.0 mm thread, 5.9 mm shank diameter; flange gaskets, 20 mm outer diameter / 6.5 mm inner diameter, 2 mm thickness; M6 hex nuts, 10 mm wrench size. All parts comply with DIN 6923 and can be installed without machining thanks to tight tolerances. The lightweight design (45 g) does not overload the exhaust bracket.
[NOISE REDUCTION & PERFECT SEAL] The graphite insert acts as a flexible lip, reducing rattles and whistling by up to 30%. Uniform pressure distribution ensures a durable, airtight seal, preventing power loss and increased fuel consumption. Integrated shock absorber extends the life of the exhaust system. [UNIVERSAL USE] Compatible with mopeds, scooters, 50cc 2-stroke mini-bikes, go-karts, and pocket bikes with the same thread. Quick installation in minutes: remove the old gasket, clean the flange, install the new kit, and tighten in a crisscross pattern to 12 Nm with a 10mm open-end wrench. Ideal for DIY enthusiasts, workshops, and budget-conscious tuning fans.
