PARKER hose fittings Germany PARKER model PARKER price

PARKER hose fittings connect different hydraulic components to form a closed-loop hydraulic system, serving as a connecting accessory. They connect various hydraulic components (pumps, delivery lines, directional valves, shut-off valves, hydraulic motors, hydraulic cylinders, and auxiliary components such as level gauges, thermometers, and pressure gauges) to form a closed-loop hydraulic system, acting as a connecting accessory.

PARKER hose fitting selection

A tee joint, literally speaking, is a pipe fitting with 3 openings. This type of hardware can transport and separate gases and liquids, and its applications are very common, such as for repairing water pipes without stopping the water supply and in metal flexible piping systems. 1. Check suitability: the selection of tee fittings first depends on the actual conditions of the water pipe. The shapes and specifications of three-way fittings vary. They are mainly divided into T shape or Y shape, with equal-diameter and different-diameter ports. Equal-diameter ports have the same diameter for all three holes; reducers are generally larger than the main pipe, and 2 pipes are smaller than the main pipe. You can choose according to your actual needs and select accessories compatible with the pipeline, preferably from the same brand. 2. Check material: materials for water pipe tee joints mainly include carbon steel, cast steel, carbon structural steel, stainless steel, copper, aluminum alloy, plastic, argon arc casting, pvc, etc. Different materials have different prices and applicability; everyone can choose based on their own situation. Buy now, but regardless of the material, first check if it is qualified. Smell for any unpleasant odors, and if purchasing carefully, check for product compliance marks. 3. Check appearance: when purchasing tee fittings, pay attention to their appearance, checking for smoothness, uniform pipe wall thickness, and clean walls. Do not choose substandard 'accessory' pipes. If it is a threaded tee joint, also pay attention to whether the external thread development and pitch are uniformly distributed. 4. Check performance: performance is the direct standard for product adoption; too low performance will affect service life. You can soak the tee joint in boiling water. If you find the water pipe loses its initial strength, then its performance is not very good.

PARKER hose fitting precautions

1. Before cleaning pipes with acidic detergents, residual welding slag, stains, varnish, and other substances must be cleaned off to prevent chemical reactions that could cause unnecessary damage to the pipes and affect future use. 2. To ensure the normal use of hose fittings, they must be protected with special care. During transportation, disassembly, or pickling, avoid damaging threads, pipelines, and sealing surfaces; the best method is to seal them with tape. 3. For all threads on the hose fittings, use acid-resistant plastic tape or rubber tape for protection. Alternatively, after direct water washing, apply dry oil to the threaded areas, let it dry, and then immerse in acid solution to remove rust spots. 4. During the pipe cleaning process, pay special attention to the markings on the pipes and protect their integrity as much as possible. Also, complete all welding tasks before pickling, and in daily life, pay attention to necessary protection work for the hoses.
