Quick Connect Air Couplings

Speedaire ARO quick-connect air couplings are manufactured to attach to air hoses and tools to compressed air supplies. They are also called Milton A-style couplings and are suitable for use on pneumatic lines in construction, factory automation and furniture building. Choose from a range of these quick-connect air couplings available in (F)NPT and (M)NPT connection types.

Speedaire quick-connect couplings are connectors or fittings designed to mate fluid lines with equipment that need frequent connections and disconnections. They are suitable for heavy-duty use and are flexible, offering more damage resistance in comparison to softer metals and a broad working temperature range. These couplings are also known as sockets and take coupling plugs to attach tools to air, water or fluid lines. Choose from a range of these couplings, available in 1/4 and 3/8 inch barb sizes.

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.

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.

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 Pioneer OEM interchange couplers and male tips provide reliable aftermarket couplers and nipples to connect specific OEM interchange quick couplings for applications in agricultural farm equipment and hydraulic loaders. They have steel construction with female NPTF / ORB threading for strength, durability and easy installations. The male tips feature hardened locking ball grooves for resistance against wear and brinelling. Choose from a wide range of these couplings, available in 1/2-14 NPTF, 3/4-16 UNF and 7/8-14 UNF thread sizes.

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 6600 Series nipples are used in hydraulic fluid systems for a secure and leak-free connection of hoses or pipes with compatible female ORB / NPTF type port configurations. They are made of steel with zinc-chromate plating for corrosion resistance and improve durability. These couplers have double shut-off poppet valves that prevent the flow of fluid in both directions and include nitrile seals to resist oils, fuels, hydraulic fluids, water and other chemicals. These nipples are designed to be interchangeable with other quick-disconnect couplings complying with ISO 7241-1 Series A standards.

Parker 6100 Series couplers are ideal for connecting with the 6100 Series nipples under pressure for hydraulic operations in oil & gas drilling, bulk liquid transfer and submersible pump applications. These low spill couplings have connection indicator grooves for indicating when the connection is complete and valves are fully open for use in fluid transfer lines. They have brass construction with steel hex / wing nut sleeves, a nitrile seal and NPTF port ends for strength, corrosion resistance and liquid-tight operations. Choose from a wide range of these couplers, available in 3/4, 1, 1-1/4 and 1-1/2 inch coupling sizes.
