Water Pump Pliers Set - Bosch, 180 and 250 mm, 2 pcs, 1600A03DN6

Bosch Professional Water Pump Pliers Set, 180 and 250 mm, 1 600 A03 DN6

The Bosch 1 600 A03 DN6 set pairs two water pump pliers - one 180 mm long, the other 250 mm. That is the usual working pair: the smaller pair reaches under a sink and between pipes, the larger gives the leverage needed for a tight union nut or an old pipe joint. The set weighs 0.562 kg.

Grip and adjustment

The gripping teeth are induction hardened to HRC 60 ±2 - that is the part which decides whether the pliers bite or slip on a chrome nut. Adjustment is by push button: the jaw width changes with one press, without opening the pliers fully. The tool conforms to ISO 8976, the standard for slip-joint water pump pliers.

Material and handles

Bosch lists carbon steel as the material in the article data. The handles are dipped, non-slip - the coating is applied by dipping, which gives a seamless covering that keeps its grip with wet hands and cleans easily of grease and jointing compound.

Applications

Plumbing and heating installation, changing taps and traps, work on pipe joints, vehicle hoses and clips, tightening large irregular nuts for which no spanner size exists.

In use

Water pump pliers grip around the circumference and leave marks - on visible chrome or polished fittings put a piece of leather or a soft cloth underneath. They are not for tightening to a specified torque and must not be extended with a pipe.
