Custom Rubber Products
KEF Corp. works with customers in development partnerships, identifying
the best custom rubber and sealing options for specific applications from
a broad choice of materials and seal profiles. With our direct experience
in unique and challenging applications positions, we offer custom design
and industry-specific development services for sealing components.
If you’re looking for unusual or odd-shaped electrometric
part or comportment to solve awkward design problem, KEF is your solution.
We work closely with our customers to find the seal materials and designs
that will maximize the performance of their products.
Our highly engineered specialties are high precision miniature
or micro-miniature custom seals and rubber products. We deliver your satisfaction
with highest quality products on time.
PROVEN EXPERTISE DECREASES YOUR COST
With over 40 years of experience in the design, development and application
of precision micro-miniature custom seals and rubber products, KEF engineering
personnel bring expertise directly to customers. Our assistance in design
and materials for applications often reduces the time from concept to
finished product when KEF engineers are consulted in early stages of design.
This expertise often increases quality and decreases cost to customers’
products.
MATERAL
We develop and formulate our materials in-house. We use our skills in
applied material technology to give you a competitive advantage. We draw
from the latest material technologies and many thousands of our own material
databases. Our staff chemists develop unique compounds to precisely match
your product requirements and business needs.
APPLICATIONS
MINIATURE O-RINGS
Completely automated molding using industrial robots provide superior
quality control, flexible production. Our small size Micro O-ring dimensions
and tolerance are:
Inside diameter: 0.4mm (0.015”)±0.03mm (0.0012 in),
Cross sectional width: 0.2mm (0.008”)±0.02mm (0.0008 in)

Watch seals
• Small electronics devices seals, rubber products
• Gas lighter (cigarette) seals
CHEMICAL RESISTANCE SEALS, RUBBER PRODUCTS
High performance materials from our own material databases for chemical
resistance are used such as:
• Alkaline batteries seals ( precision shape and size
are provided)
• Fuel dispensers
We develop and formulate ink resistance rubber material,
extremely made flat surface & parallel cap for ink jet printer. This
flat surface provides tight seal for ink tank to avoid drying ink and
ink resistance material provides outstanding high performance and long
life.
• Ink Jet Printer-Wiper
• Ink Jet Printer-Cap for ink tank
LOW CONTAMINATION AND OUT-GASSING SEALS, RUBBER
PRODUCTS
Class 100 Clean Room Facility for ultra high purity, cleanliness, minimal
contamination & extremely low out-gassing rubber components- all these
characteristics contribute to reliability and long life of KEF micro-seals.
KEF micro-seals can be used such as:
 •
HDD shock absorbing rubbers (avoid head crash)
• Semiconductor manufacturing process seals, rubber products
CUSTOM MOULDINGS RUBBER PRODUCTS
Custom moldings are available in a range of sizes from 0.2mm (0.008 in)
to 500mm (19.7 in) in diameter. Moldings can be manufactured to the customer's
specifications. Moldings can be formed into most complex shapes for any
application required.
