Diagnostic, Orifice, Bleed Adapters and Specialty Fittings

Product catalog summary
Introduction
Parker Hannifin Corporation provides a range of specialty adapters for diagnostic, flow control, and bleeding applications. These include in-line diagnostic tees, pressure gauge connectors, and diagnostic tips compatible with both electronic and mechanical diagnostic equipment. The catalog also includes fixed flow control orifice fittings, bleed adapters for hydraulic systems, and screen fittings for added protection.
Diagnostic Fittings and Adapters
  • In-Line Diagnostic Tees: These tees are designed for ORFS and 37° flare interfaces, allowing unlimited positioning with elastomeric sealing. They are compatible with Parker's diagnostic tools and Senso-Control® equipment, used for pressure and temperature measurements, oil sampling, and diagnostics without removing port adapters. They can be reused for 10-20 remakes at full pressure, with recommended assembly torques provided.
Pressure Gauge Adapters
  • BSPP Diagnostic Pressure Gauge Adapters: These adapters are available for ORFS, 37° Flare, and 24° Metric Flareless connections, using BSPP threads and sealing washers.
  • NPT and SAE-ORB Diagnostic Pressure Gauge Adapters: Designed for North American connections, these adapters attach pressure gauges to hose swivel ends or tees for in-line diagnostics.
EO Diagnostic Swivels
EO Diagnostic Swivels are used on EO tees for periodic pressure and temperature checks, featuring a diagnostic tip compatible with Parker's SMA3 diagnostic nose.
Orifice Fittings
Orifice fittings control flow in hydraulic systems, specified by orifice size and pressure ratings. They allow OEMs to pre-set specific orifice sizes, eliminating the need for costly flow control valves. Key features include 37° flare and ORFS configurations, three standard body sizes, and options for permanent or temporary installation. Applications include fixed rotation speed for hydraulic motors and fixed speed on cylinder extend or retract.
Direct Port Orifice Fittings
Parker offers custom orifice adapters to replace traditional port adapters, available in various configurations.
Bleed Adapters
These adapters are designed to safely bleed hydraulic systems without "cracking" connections, using a standard automotive bleed screw design. Installation should be at the highest point in the system, and bleeding should be done at low pressure.
Parker Triple Thread Fittings
These three-piece hydraulic flared fittings are used in various applications, including diesel engines and transportation air conditioning lines, though largely replaced by the standardized 37° flare connection.
Screen Fittings
Screen fittings protect against particles in hydraulic systems, used with filtration systems, and available with screens retaining particle sizes from 480 to 65 microns. They have bi-directional flow capacity and require regular cleaning.
Pressure Ratings and Ordering
Screen fittings have the same dynamic pressure ratings as their equivalent fitting bodies. For ordering, contact the Tube Fittings Division.

Diagnostic, Orifice, Bleed Adapters, Screen and Specialty Fittings 4300 Catalog Bleed Adapters Entrapped air is a major contributor to inefficient operation. Typically, bleeding hydraulic systems is done by “cracking” a connection to “bleed off” the entrapped air. This practice is not recommended, especially in larger size fittings where high forces can exist. Parker’s bleed adapters are especially beneficial in applications where elastomeric seals (O-rings) can be extruded and/or damaged during bleeding such as with Parker’s Seal-Lok fittings. Parker’s bleed adapters are designed specifically...
