Two e- catalogs are finished last week, one is showing products such as fittings, hoses, ferrules with drawing and detail technical data; the other is explaining machines can be found in YH Hydraulic factory which includes hose crimper machine, nut crimper machine, hose cutting machine, testing machine, tube expanding machine, etc.. Before, we only have catalogs in book edition that causes difficulties in communicating with customers abroad. So we spent about 3 months in collecting product data to finish e-catalogs. If you require products catalogs, you can download from this website.
