The Fabulous Five

Across North America, there are five popular quick coupling styles that serve a wide variety of mobile and industrial applications.

df series

DF Series

  • Interchangeable with Parker 20/30-Series and other MIL-C-4109F/ISO6150B couplings
  • Automatic couplers have a reverse-acting sleeve for easy connection and safe one-handed disconnection
  • Manual couplers have a sleek profile, with sleeve-guard lip to prevent accidental disconnection
  • Available in steel, brass, and 303 stainless steel
  • Available in sizes 1/4" to 3/4"
h series

H Series

  • Interchangeable with Parker 60-Series, Danfoss/Hansen HK-Series, and Faster HNV-Series
  • Standardized product variations available to meet the requirements of slide-gate, food service, and steam applications
  • Meets or exceeds ISO7241 Series 'B' performance requirements
  • Wide variety of material choices, including: steel, brass, 303 stainless steel, and 316 stainless steel
  • Available in sizes 1/8" to 2-1/2"
k series

K Series

  • Interchangeable with Parker 6600-Series, Faster ANV-Series, and Danfoss 5600
  • Meets or exceeds ISO7241 Series 'A' performance requirements

  • O-ring full-connection indicator will remain highly visible, despite operation in dirty environments, allowing operators to ensure the parts are fully connected, maximizing the performance of their systems
  • Brass construction ensures optimum corrosion resistance, while the high tensile steel components resist failure associated with pressurizedflow connection/disconnection and surge flow conditions
  • Innovative hybrid valve guide design provides industry leading flow and pressure performance
  • Full hex on both coupling halves for easy installation

Quick Coupling Selection Guide

1. Determine the profile (shape) of the plug using the chart below to determine if it is pneumatic or hydraulic:


2. Body size dimension charts can be found within each series section. Measure the A (diameter) and B (tip length) dimensions to determine the plug body size.

body size

3. Use the industry standard thread chart below to determine the end connection thread size. If you have a hose barb, the ID measurement of your hose will determine the barb size (figure 2).
