Construction information
A Schrader® valve consists of Materials
a hollow cylindrical metal tube, Brass, Stainless Steel
typically brass, with the exterior end Sealing Materials
threaded. The interior end form varies Polychloroprene, Nitrile-Butadine, Hydrogenated Nitrile-
depending on the application of the Butadine, Fluorocarbon, EDPM, Elastomer
valve. In the center of the exterior Finish
end is a metal pin pointing along the No Plating, Nickel or Tin plated Brass
axis of the tube; end of the pin is Valve cores are defined by their characteristics, and
approximately flush with the end depending on the type selected, these characteristics vary
depending on the material, the finish and the design of each

through.
Most Schrader® valves used on tires have threads and bodies
with a standard exterior size allowing for universal caps and tools • Minimum and Maximum Travel This is the

nitrogen, R12, R22, R134a, oils, Halon, SF6, Petrols, butane and
propane, and any
other controllable media.
The valve core is made up of 3 main pieces:
• The bridge for screwing the valve core into its housing.
• The seat with its joint providing a static seal from the valve
body.
• The valve with its spring for introducing or draining fluid
and guaranteeing sealing under pressure in the rest
position.
Valve Cores
All Schrader® valve cores are compatible with existing U.S.A. standards, manufacturing valves for air tanks, steel barrels,
compressors and other pneumatic containers where dependable automatic valves are needed. Schrader also offers a variety of
service tools to install, remove or repair valves.
OEM sales information: Available worldwide in medium to high quanities. Application specific orders welcomed.
Aftermarket sales information: Schrader offers a range of standard, large bore, airplane and special valve cores through the
aftermarket/replacement sector.

Valve Core Installation
Installation Guide Cleanliness
Cleanliness for the Valve Cores and Body must be less than 0.015 grams
Scope per 100 parts after final assembly. Using improper torque drivers can cause
contamination.
This engineering guide is to cover the installation and application
recommendations for the use of standard valve cores in all automotive and Standard Core Drilling
industrial applications.
Core chamber must conform to ISO 7442 and threads must be to
Product Type ISO 4570/1
Standard valve cores are defined by ISO (International Standards
Organization), TRA (Tire & Rim Association) and ARI (American
Refrigeration Institute) relative to the application for air, fluid and gas
service devices.
Installation Torque
All Valve Bodies must conform to the TRA, ISO or ARI recommended
standard core drilling to ensure proper seating of the Valve Core to meet the
sealing and pin height requirements of the individual industry standards.
Surface Finish
The importance of a properly machined housing cannot be overemphasized.
The surface finish of the taper seat must be smooth without any machining
tool marks. The proper taper seat angle must also be met to ensure proper
compression of the outer Valve Core sealing material.
Serviceability
No Valve Cores are to be reused under any circumstances after removal
from the Valve Body. Always install a new Valve Core when servicing
the system for air, fluid or gas applications.
The installation torque for standard cores per ISO is 3 – 5in. lbs. [0.34 –
0.57 Nm]. Breakaway torque is not an accurate way to verify the installation
torque due to material, lubricants and other conditions that may exist.
Torque Drivers
For automated assembly, it is recommended to use only drafted torque
driver bits that are more forgiving reducing the damage to the valve core
creating chips that may cause leaks in the final assembly.
Temperature Sensitive
It is not recommended to submit the Valve Core assembled into a Valve
Body to accelerated temperatures above the normal operating temperatures
such as brazing and oven curing for paints and other coating processes.
Permanent damage to the seals may occur causing long term sealing
problems.

Valve Tools
The right tools for the job Torque wrench insures that valve cores are
installed to the proper torque.
Proper core installation is important to ensure correct pin
height and leak free performance. Schrader recommends
that tools designed specifically for the task be used. Schrader
offers a variety of purpose driven tools for the job.
