Tokyo Marui 4.3 Hi-Capa Y Ring (H43-26)
This is a genuine Tokyo Marui replacement part for the Tokyo Marui 4.3 Hi-Capa gas blowback pistol, listed as the Y Ring under part number H43-26. The 4.3 is the compact member of Tokyo Marui’s Hi-Capa family, with a shorter slide and barrel than the 5.1, and many of its internal parts are specific to it.
Tokyo Marui is the Japanese maker whose Hi-Capa design is the basis of a huge number of pistols and upgrade parts. When a small internal part is lost or damaged, a genuine replacement from the original maker is the most reliable way to get the pistol working properly again.
Compatibility
Genuine Tokyo Marui parts are made for specific models, and copies of the same design from other brands do not always use identical parts. Check the part number against the exploded parts diagram in your pistol’s manual before ordering, and contact us if you are not sure.
Care and maintenance
Fit the part with the pistol’s magazine removed and the gas fully emptied, working on a clean, well-lit surface where small springs and pins cannot roll away. Follow the order shown in the manual and never force a part into place.
Once fitted, apply a very light film of silicone oil to moving parts, wipe away any excess, and function-check the pistol before filling a magazine with gas.
Who is it for?
Ideal for owners of the Tokyo Marui 4.3 Hi-Capa who need to replace a lost or damaged Y Ring, and for technicians who keep genuine TM spares in stock.
Please note: Supplied as the single part only. Please confirm the part number against your pistol’s parts diagram before ordering.
