Parker PDP Series Test Port Couplings

PDP Series couplings provide easy connection for mechanical gauges or specialized diagnostic equipment like SensoControl.

Typically, PDP nipples are permanantely mounted in the system at threaded test ports, in rigid tubing or in hose assemblies. PDP couplers are attached to test instruments.

Locking balls align the couplers to the mating nipples without threading, so gauges, transducers and other test equipment can be snapped into place without difficulty.

Parker's PDP Series couplings offer the advantages of PD couplings, but are designed to connect easily and quickly under full system pressure up to 6000 PSI (operating).

PDP couplers and nipples push to connect with a constant force of only six pounds. Then the coupler base is turned to open the valve and complete the connection. In the connected position, the coupler base blocks the retracting sleeve to prevent accidental disconnects.

Features

Made to connect under pressure up to 6,000 PSI
Grip-tight knurled sleeves help to make connecting and disconnecting easy, even while wearing gloves.
Nipples are machined from high tensile steel for strength to withstand 6,000 PSI continuous operating pressure.
End connections include pipe, O-ring, 37° Flare and ORFS.
Durable Ball Valve Nipple
Coupler is unvalved to allow gauges and transducers to return to zero when disconnected.
