[The Surevalve ™ will replace most conventional valve stems to provide an exceptional level of safety, security, appearance, and durability. The Surevalve ™ has a unique two piece patented design which incorporates a break-away outer valve stem and a lower base valve. The valve core sits subriminal in the base valve for greater protection. If the outer stem is ever severed the valve is designed to retain air in the wheel. The two piece design also allows for outer stem replacement without removing the valve stem or tire. Surevalve ™ is a tire saver and a life saver...because air matters ™.]
[This site contains an installation video and installation picture page to help aid tire installation professionals in the installation of Surevalve ™. HCW Services, Inc. strongly recommends that installation be performed by a tire installation professional. Improper installation can lead to serious injury or even death.]
[Most questions can be answered by the contents of this site. If in the event you still can't find the answer that you desire feel free to contact us at support@hcwsinc.com.]
[We find that in most cases a leaking base valve is the result of the base valve not being tightened properly in the rim. The base valve should be installed tight enough where it won't spin when the outer break-away stem is installed. After installation it is recommended that the valve assembly be checked with a soap and water mixture for any signs of bubbles indicating a leak. In the event that a leak is detected, tighten the base valve some more to squash the rubber grommet and provide a leak-free seal. We do not have a torque spec for installation due to the many rim configurations making it impossible to determine the proper torque for every application.]
[The two rubber grommet sizes that come with Surevalve ™ are a .453 inch grommet and a .625 inch grommet. The .453 inch grommet is the size of a conventional valve stem found on most tires. The .625 grommet is for use in the larger hole found on most motorsport racing rims .]
[Most automotive and tire facilities can install Surevalve ™. It is highly recommended that only a tire installation professional install Surevalve™ because improper installation can cause serious injury or even death. Please refer to OSHA std 29 CFR 1910.177 for servicing single and multi-piece rims.]
[The Surevalve ™ has no life rating . It should be replaced in the event of a leaking valve or visible defects or damage, otherwise you should enjoy years of use from your Surevalves ™.]
[Surevalve ™ is compatible with nitrogen but it is recommended that the Surevalve ™ be installed in the rim and checked for leaks prior to the nitrogen fill process.]
[Surevalve ™ is rated for applications up to 200 psi.]
[Although the outer valve stem has
threads, it is recommended that you
check the cap to outer stem clearance
before you install caps on them.
The way to check the clearance is to
install the cap on the outer stem while
it is off the base valve and see if the
plunger moves at all when the cap
bottoms out. If the plunger moves
it is not recommended that you use that
cap on the outer break-away stem.
Many caps also have an inner seal which
can be removed to provide additional
clearance. The outer valve stems are double sealed to prevent air, dirt, and moisture from penetrating the valve core
there fore the additional seal in the
cap is not necessary. The outer
valve stem functions like an extension
to the base valve, caps that depress the
plunger down could open the valve core
in the base valve that is why it is
important to check the cap to outer
valve stem clearance. Nitrofill
™
caps with the seal removed work very
well and look great. Try to avoid
the use of plastic caps.]
[Surevalve ™ is not compatible with the tire pressure sensors which are incorporated in the valve stems at this time. However Surevalve ™ will work with the factory tire pressure monitors which are not part of the valve stem like the ones mounted on the inside of the rims. Please refer to your vehicles owners guide to see if your vehicle is equipped with tire pressure sensors]
[The Surevalve ™ caps are installed by removing the outer break-away stem after the tire is properly inflated and installed onto the base valve, in the outer stems place. The outer break - away stem will still be necessary to add air to the tire assembly due to the large diameter of the base valve.]
[The Surevalve ™ is a safety device and not a tire bleeder. They should be legal for most motorsport racing. Surevalve ™ has been approved for NASCAR competition. Surevalve ™ is approved for the Fastruck Racing Series. Surevalve ™ is approved by the ASA, ARCA, and PASS. Surevalve ™ has also been approved by the SCCA and SVRA. It is also allowed in ALMS and IMSA competition and many more. ]
[The Surevalve ™ can be installed with some simple hand tools. You will need a 9/16 and 1/2 inch semi deep or deep socket, a ratchet and a 3/16 hex or allen wrench. ]
[The Surevalve ™ can be checked for leaks after installation by inflating the tire on the rim and using a soap and water mixture applied to the valve area. If any bubbles are detected dismount the tire and tighten the Surevalve ™ base valve remount the tire and repeat the leak check procedure. ]
