Jonal Laboratories

Custom High Temperature Elastomeric Silicone Rubber Aerospace Seals

Jonal makes products for people who can't afford failures!

From the inner space of nuclear power to the edge of the universe, Jonal Laboratories has made a material difference.  They have formulated and fabricated exotic materials and products into standard shapes, highly complex shapes, diaphragms, masks and electromagnetic shields.  More importantly, they have helped shape ideas vital to defense, energy, communications and transportation.  Jonal can provide fast turnaround of prototypes and samples at an extremely competitive cost.  They understand their customers can't afford failure.

Jonal is results-oriented.  Jonal applies three essential ingredients to every compound they formulate and every product they manufacture, from concept to prototype.

The first is over four decades of experience meeting AMS, ASTM, Mil-Specifications and the most demanding company proprietary specifications.

The second is technology.  The most versatile and cost-efficient manufacturing techniques enable Jonal to respond on time and within budget.  Highly advanced production and machinery ensures consistency and scheduled delivery.

The third is a commitment that Jonal's elastomer products meet or exceed our customer's expectations for performance.  Strict quality control procedures include:

  • ISO-9001/AS-9100

  • Incoming Material Testing & Inspection

  • Process Controls

  • In-process Inspection

  • Continuous Product Testing

  • Final Inspection

Jonal’s primary mission is to solve elastomeric sealing problems. For over 40 years, aerospace engineers and designers have partnered with Jonal for creative, reliable, producible sealing solutions. Jonal makes products for people who can't afford failures.  Contact SVS-Engineering (781-944-8073) for a quote or for more information on any of the Jonal products listed below.

Custom Molded O-rings / O-ring Seals

A leader in elastomer technology, Jonal has the ability to meet the rigorous criteria of temperature, fluid, ozone and rubber-to-metal bonding requirements.

Jonal has confined their O-ring work to only applications that call for High Temperature, Challenging Environmental Issues or Special Compounding/Chemical requirements. If your requirement is difficult to meet, Jonal is the company that will meet your needs.

Complex Elastomer-to-Metal Bonding

Does your application require:

  • -200F to 600F Temperature range

  • Fluid Resistance

  • High and Low Vacuum Pressures

  • Hydrolic Stability

  • Gas Impermeability

  • Ozone Resistance

  • Thermal/Electric Insulation or Conductivity

  • EMI or RFI Shielding

  • Elastomer-to-Metal Bonding

  • Vibration Damping

  • Flange Sealing

  • Tight Tolerance O-Rings with Super Quality Finish

  • Masking

  • Extruded Shape

Reinforced and Non-Reinforced Diaphragms

Specialty compounds are formulated using the following base elastomers:

  • Silicone

  • Fluorosilicone

  • Fluorocarbon...Fluorel...Viton

  • Urethane (castable, millable, foam)

  • Nitrile (Buna-N)

  • Carboxilated Nitrile (XNBR)

  • Hydrogenated Nitrile (HNBR)

  • Chloroprene (Neoprene)

  • Butyl

  • Ethylene Propylene

  • Epichlorohydrin

  • Acrylate

  • Styrene-Butadiene (SBR)

  • Natural Rubber

Reinforced and Non-Reinforced Diaphragms

Custom seals incorporating internal and external reinforcements have been developed by Jonal for use in engine inlets, wing to fuselage seals, and canopies.

Precision molding and fabricating techniques have long been one of Jonal's many strengths as a supplier of high quality, close tolerance seals.  Electronic configuration analysis and material testing prior to fabrication ensures that the product meets the physical properties required for both structural integrity and performance requirements.  Secondary operations such as water jet cutting are available for those designs requiring post molding operations.
