Reducing Fittings
A reducing fitting sits between two threads of different size, one in the component and one on the line. Check thread form and nominal size separately, because parallel G threads and tapered NPT threads are not interchangeable. If one side is wrong, assembly fails or the joint leaks under operating pressure.
FAQ
Frequently Asked Questions
Which materials are reducing fittings available in?
PTS supplies reducing fittings in stainless steel (e.g. 1.4571) and steel, with further materials on request. Material choice depends on the medium, operating pressure and corrosion requirement.
Which thread sizes are available?
From G1/8 to G2 plus metric and selected NPT combinations. The exact thread combination for each fitting is listed in the article technical data.

Snap-tite Quick Couplings
A quick coupling is always two halves, and both must come from the same series. A coupler and nipple from different series will sometimes mate mechanically but will not seal reliably. The part number carries series, size and connection in that order; the combination each article uses is listed in its technical data.
Parker Ermeto Cutting Ring Fittings
Ermeto is the Parker cutting ring fitting system for tube lines to DIN 2353. As the nut is tightened the ring bites into the tube, creating grip and seal in one step. Tube outside diameter and series are chosen separately: L for the light, S for the heavy version. A complete joint needs body, ring and nut from the same series.
Counterbalance Valves
During lowering the counterbalance valve does the braking work, so the lowering speed is set by the control system and not by the load. If that braking action is missing or the valve is wrongly sized, the load sags on start-up and the lowering motion turns jerky.
Bladder Accumulators
A bladder accumulator is a hydropneumatic pressure vessel: inside the steel shell, an elastic bladder separates the nitrogen-precharged gas side from the oil side. When system pressure rises the accumulator takes in oil, and when it falls it gives the oil back. That is how you store energy, damp pulsations, absorb pressure surges or compensate for leakage losses. Four figures narrow the selection: nominal volume, permissible working pressure, port and the elastomer of the bladder, which has to suit the medium and the temperature. Typical nominal volumes range from about 4 to 50 litres with pressure ratings up to 350 bar. PTS supplies bladder accumulators from Parker Olaer, HYDAC and Bosch Rexroth from stock, plus mounting clamps, seal kits and replacement bladders, so an accumulator can be repaired instead of replaced outright.
