The TXL series taper-bush jaw coupling is designed for European-standard small-to-medium fluid pumps, industrial oil pumps, and refrigeration compressor units. Its defining feature is an extremely axially compact structure combined with taper-bush locking, which perfectly solves the long-standing pain point of traditional pump couplings being very troublesome to service.
| Item | Specification |
