Quick Couplings

Hydraulic Couplings | Snap-Tite Design

Parker offers the H Series and PH Series Snap-tite design couplings for hydraulic applications. In the H Series couplings, the poppet valve enables single or double shut-off valving. PH version couplers and nipples are valved with a connect-under-pressure feature. These steel couplers and nipples allow connection with H Series valved couplers and nipples when there is a residual pressure on the PH coupler/nipple side. It is recommended that only one half of the connection (coupler or nipple) be PH version, not both. Applications include industrial hydraulic lines, water and coolant lines, and mobile equipment.

Hydraulic Quick Couplings | Diagnostic Test Port

Parker’s PD Series diagnostic test port couplings provide easy connection for mechanical gauges or specialized diagnostic equipment like SensoControl®. Grip-tight knurled sleeves help to make connecting and disconnecting.

Non-Spill Hydraulic Quick Couplings

Non-spill couplings are designed to minimize spillage and air inclusion when connecting or disconnecting. Parker’s line of non-spill couplings includes Series FF/FC, FEM/FEC, FS, FH, and NS.

FF Series couplings have a sleeve locking mechanism prevents accidental disconnection. FF Series couplings are widely used in the public utility market where hydraulic oil spillage can constitute a serious safety hazard, particularly in overhead bucket hoists that are used for maintenance of high-voltage power transmission lines. FC Series nipples provide a connect-under-pressure option for trapped pressures up to 3000 psi on the nipple side. * Note: FF Series 3/8″ parts numbers will be phased out and rationalized with FEM Series part numbers. Historically, the FF and FEM in the 3/8″ size have been interchangeable. *

FEM series couplings are designed to meet the stringent design and pressure requirements of ISO 16028 and are used where hydraulic spillage is a concern and global interchangeability with other manufacturers is important. The FEC Series nipple provides connect-under-pressure capability with up to 3000 PSI of trapped pressure in the nipple and are ideal for applications where residual pressure makes reconnect difficult. * Beginning November 2020, FEM Series couplings are undergoing a redesign. View FEM Series Redesigned with Enhanced Features and Benefits bulletin. *

FS Series stainless steel couplings have double shut-off flush mating valves that are suitable for sealing off media in chemical processing, chemical dispensing, food processing, and other corrosive applications.

FH Series high pressure couplings are an innovative product combining the advantages of a flush-face design with a highly technical performance of a rated pressure of 10,000 PSI.

NS Series Couplers and nipples are steel with nitrile seals. They utilize a PTFE back-up ring as additional support to the interface seal. Available in 1/2 inch through 1 inch
sizes.
