Quick Connect Air Couplings

Parker H Series multi purpose quick couplings are suitable for fluid transfer in hydraulic, water & coolant lines for high pressure fluid transfer operations. These nipples are ideal for oil & gas facilities & construction sites and feature durable aluminium construction for withstanding high pressures up to 2250 psi and temperatures up to 250 degrees F. Choose from a wide range of these nipples, available in male & female thread connections.

Parker PDP Series nipples with compatible couplers provide easy connection for specialised diagnostic equipment or mechanical gauges. These high tensile steel units provide excellent strength and capability to withstand 6000 PSI continuous operating pressure and grip-tight knurled sleeves for making quick connection / disconnection while wearing gloves. They are aligned with the mating couplers via locking balls to eliminate the need for threading and easily snap the test equipment (like gauges, transducers) into place with zero difficulties. These nipples are permanently mounted at the threaded test ports, rigid tubings or hose assemblies and are available in UNF, Seal-Lok, NPTF and Triple-Lok type connections.

Speedaire quick-connect couplings are connectors or fittings designed to mate fluid lines with equipment that need frequent connections and disconnections. They are also known as sockets and take coupling plugs to attach tools to air, water, or fluid lines. These steel couplings are heavy-duty and are flexible having more damage resistance in comparison to softer metals and a broad working temperature range.

Parker PD Series nipples connect with the PD Series couplers under push-to-connect operation for hydraulic & pneumatic applications in fluid or air system maintenance & troubleshooting, mobile equipment engines, cooling systems and industrial hydraulic systems. These non-spill couplings with flush face valves reduce spillage and entry of air while connecting or disconnecting fluid lines. They have steel construction with zinc & clear trivalent chromate plating and a nitrile seal for corrosion resistance, thereby preventing entry of dust and withstanding a maximum operating pressure of 6000 psi. Selected models have bulkhead end fitting configurations for specific system installations and panel mounting. Choose from a wide range of these male / female threaded nipples with NPTF, UNF, Metric, Triple-Loc or Seal-Loc port end connections.

Parker fluid sampling test port couplings provide easy access points for obtaining fluid samples in applications like cooling systems, mobile equipment engines and system performance optimisation. These steel couplers or brass nipples come with fluorocarbon seals offering durability, thermal and chemical resistance and their quick connect design prevent unscheduled maintenance, costly repairs, and production downtime. Selected models are installed in low pressure or return lines for accurate analytical measurements. Choose from a wide range of these test port quick couplings, available in 7/16 to 20 inch (ORB) and 1/4 to 18 inch (NPTF) thread size connections.
