Parker hydraulic quick couplings

Parker Hannifin Corporation is the global leader in motion and control technologies, providing precision-engineered solutions for a wide variety of mobile, industrial, and aerospace markets. With more than a century of experience, we are often called to the table for the collaborations that help to solve the most complex engineering challenges.

A hydraulic quick coupling enables rapid quick connection and disconnection of hydraulic lines or hoses. It consists of 2 parts to purchase individually: a coupler (female) and a nipple (male). These couplings ensure stability during operation, thanks to a sealing mechanism to prevent leakage, and easy quick release for maintenance without special tools.

Parker provides a comprehensive selection of hydraulic quick couplings designed for hydraulic and fluid transfer applications and offers a variety of standard and interchangeable profiles to accommodate various body sizes and connection types:

  • Popular body sizes: 1/8", 1/4", 3/8", 1/2", 3/4", 1", 1-1/2"
  • Female couplers with barbed connection (popular sizes: 1/4", 5/16", 3/8", 1/2", 3/4"), threaded connection (popular threads: 1/8" NPT, 1/4" NPT, 3/8" NPT, 1/2" NPT, 3/4" NPT), or O-Ring Boss (ORB) connection (popular sizes: 9/16" UNF, 3/4" UNF, 7/8" UNF)
  • Male nipples with threaded connection (popular threads: 1/8" NPT, 1/4" NPT, 3/8" NPT, 1/2" NPT, 3/4" NPT), O-Ring Boss (ORB) connection (popular sizes: 7/16" UNF, 9/16" UNF, 3/4" UNF), O-Ring Face Seal (ORFS) connection (popular sizes: 1/4", 3/8", 1/2"), or JIC 37° flare (popular sizes: 1/4", 3/8", 1/2")

    • Below is our e-catalogue for hydraulic quick couplings with individual product information and datasheets, recommended couplers or nipples, and technical characteristics filters. Those couplings are often paired with a hose and its selected crimp fitting.

    We also offer hose fabrication, crimping, and assembly with the below quick-coupling and repair services in our shops near you. We have regularly tested/calibrated the latest-generation parker machines and qualified technicians.
