HEAVY DUTY LOCKING

FLAT FACE THREADED COUPLER

threaded flat face couplers

Most popular solution for hydraulic circuit applications subject to high pressure impulses, and circuits which experience residual or trapped pressure in a line. This thread-to-connect design eliminates premature wear or brinelling.

VEP

The VEP series is a popular solution for hydraulic circuit applications subject to high pressure impulses and circuits which experience high residual or trapped pressure in a line. Thread-to-connect design eliminates premature wear or brinelling, a patented internal valve allows connection/disconnection with high residual pressures, and the flat face design avoids loss of hydraulic fluid and contamination into the circuit. A yellow o-ring indicator makes the VEP series even easier to work with.

Features
  • Size range: 1/4” thru 2”
  • Port options: NPT, SAE, BSP, ORFS
  • Interchanges with VEPHD, VEPHDL Series
  • Connect/disconnect up to 25 MPa/3625 psi residual pressure
  • Working pressure: 35-60 MPa/5075-8700 psi range
  • Eliminates brinelling, reduces leakage
  • Saves time changing tools
Applications
  • All construction equipment applications with higher pressure requirements or connection/disconnection issues with tool attachments under residual pressure
  • All large equipment needing junction points in circuit: cranes, drilling machines, oil field, well head drives, porta-power
  • Excavators w/ auxiliary line for attachments: thumbs, grapples, hammers, compactors/hopaks

VEPHD

The VEPHD (heavy duty) series offers the same features of the VEP series, with upgraded material, a yellow o-ring visual ID, and larger mating areas. Like the VEP, the VEPHD is a popular solution for hydraulic circuit applications subject to high pressure impulses and circuits which experience high residual or trapped pressure in a line, offered in a more durable, higher grade of steel and all QPQ plating for increased longevity.

Features
  • Size range: 3/4” thru 1 1/2”
  • Port options: NPT, SAE, Flange Ports
  • Interchanges with VEP, VEPHDL Series
  • Connect/disconnect up to 25 MPa/3625 psi residual pressure
  • Working pressure: 40-55 MPa/5800-7975 psi range
  • Higher grade of steel for longer life
  • Eliminates brinelling, reduces leakage
  • Entire body in QPQ
  • Wrench flats on the male for ease of connection
Applications
  • High impulse mobile circuits
  • All construction equipment applications with higher pressure requirements or connection/disconnection issues with tool attachments under residual pressure
  • Excavators w/ auxiliary line for attachments: thumbs, grapples, hammers, hydraulic compactors, hydraulic tampers, demolition

VEPHDL

The VEPHDL series heavy duty locking flat face coupler is the ultimate failsafe solution for the
most demanding hydraulic applications. This locking female version is interchangeable with standard VEPHD series flat face thread-to-connect heavy duty couplers and features a visual connection indicator for foolproof connection, every time.

Features
  • Size range: 1” thru 1 1/2”
  • Port options: NPT, SAE, Code 62 Flange Ports
  • Interchanges with VEPHD, VEP
  • Connect/disconnect up to 25 MPa/3625 psi residual pressure
  • Working pressure: 40-50 MPa/5800-7975 psi range
  • Locking heavy duty series with visual connection indicator
  • Failsafe leak-free connection
Applications
  • Most demanding hydraulic applications: high pressure, high impulse
  • Heavy duty applications where vibrations and torsion are present
  • Mobile excavation and construction: backhoes, loaders, excavators
  • Anywhere failsafe connection is critical

VP

The VP series auto-lock sleeve flat face coupler is the most popular solution for high residual pressure. With an auto-lock sleeve and the ability to connect/disconnect with high residual pressure, the VP series provides positive secondary retention in hydraulic circuit applications subject to high pressure impulses and circuits which experience high residual or trapped pressure in a line.

Features
  • Size range: 1/4” thru 1 1/2”
  • Port options: NPT, SAE, BSP, Flange Ports
  • Connect/disconnect up to 25 MPa/3625 psi residual pressure
  • Working pressure: 40-60 MPa/5800-8700 psi range
  • Safety auto-lock sleeve provides positive secondary retention
Applications
  • All construction equipment applications with higher pressure requirements or connection/disconnection issues with tool attachments under residual pressure
  • All large equipment needing junction points in circuit: cranes, drilling machines, oil field, well head drives, porta-power
  • Excavators w/auxiliary line for attachments: thumbs, grapples, hammers
