4Pcs DX5/DX7 Capping Top for Roland FH-740 RA-640 VS-640, High Sealing Anti-Leak Replacement Capping Unit for Roland 5th Gen Printhead Printers

Sealed and leak proof to prevent nozzle loss: It forms a tight vacuum fit with the fifth generation Roland FH-740/RA-640/VS-640 nozzles, effectively blocking air from entering the ink path system and reducing nozzle ink breakage, blockage, and leakage problems from the root.
Accurate adaptation without tool installation: no need to adjust the ink stack position, can be directly replaced and installed by unpacking; Not only is it perfectly compatible with Roland FH-740/RA-640/VS-640, but it is also compatible with brands such as Muto JV33 and Mimaki JV5 with the same specifications of DX5/DX7 fifth generation nozzle printers.
Corrosion resistant and aging resistant material: The surface is treated with Teflon anti sticking to prevent ink residue from clumping and damaging the nozzle surface; The material is made of weak solvent, water-based, stable and durable materials, with a service life extended by more than 30% compared to ordinary plastic ink pads, reducing the trouble of frequent replacement.
Gradient pores efficiently absorb ink and improve printing stability: Innovative upper layer micro pores+lower layer dense gradient pore structure, high ink absorption rate, quickly adsorb residual ink from the nozzle; At the same time, the dense structure of the lower layer locks the ink to prevent backflow, avoiding problems such as image breakage and color difference caused by unstable ink path pressure.
4 pieces of independent packaging: all use independent dust-proof sealed packaging, which can be used immediately without getting dirty and is convenient for storage and backup.
