JETSEAL has the largest selection of seal cross-sections
in the industry. JETSEAL’s goal is to provide our
customers with a full line of quality sealing products
at competitive prices.
JETSEAL’s industry standard seal profiles include:
• C-Seal (JC)
• E-Seal (JE, JH, JW, JX, JZ)
• V-Seal (JV)
• Omega Seal (JM)
JETSEAL’s patented profiles include:
• Super C-Seal (JC)
• Lever Seal (LE, LI)

Jetseal is on the cutting edge of sealing technology
with the uniquely designed and patented Lever Seal.
This seal can be used in any application where
enhanced springback and excessive flange movement
or flange distortion handling is needed. Regardless
the requirement, the Lever Seal will out perform any
other seal at a competitive cost.

Our in-house engineering and tool making capabilities,
coupled with an extensive inventory of raw materials,
allow us to quickly complete new designs and specialty
parts. Our experience working with engineers early
in the design process results in the most cost effective
seal solution for a given application.

The Lever Seal is superior to other “high deflection”
seals available. Due to its unique stress-distributing
design, the Lever Seal can handle three times the
flange movement of a single-ply standard E-seal with
the same sealing capability. This makes it a good
choice where thermal relaxation is a factor.

• Quality high performance sealing products
• Competitive prices
• Custom sealing solutions
• Shortened delivery times
• Excellent customer service

Available to fit any manufacturer’s E-Seal cavity,
JETSEAL’s Lever Seal comes in all common materials,
including alloys 718, X-750, Elgiloy and Waspaloy. The
Lever Seal’s cost is only marginally higher than that of
standard E-Seals, and considerably lower than that of
any other highly resilient seal.
The Lever Seal’s allowable deflection is almost double
the industry’s next best seal. Why settle for a seal that
starts with a free height of 0.121” and compresses to
0.088” when for less cost you can install a Lever Seal
with a free height of 0.145” in the same cavity. A twoply Lever Seal design will allow for substantially greater
deflection handling capabilities, and is available for even
more demanding applications.

Jetseal’s strong background in the aerospace industry
has defined our commitment to excelling in quality.
Jetseal is ISO 9001:2000 and AS9100 certified and
capable of meeting high quality and performance
standards.
