Rubber Hatch Seal Case Study

military vehiclesRubber hatch seals for military vehicles don’t just keep out wind, water, dirt, and mud. They need to withstand extreme temperatures and various weather conditions. Hatch seals must avoid compression set, too. If a vehicle’s hatch causes a rubber seal to over-compress, the part won’t provide proper sealing. Ultimately, this permanent deformation creates a gap and causes seal failure. That’s bad news for military vehicles and the highly-trained personnel who operate them.

In this case study from Elasto Proxy, you’ll learn how we solved a sealing challenge for a manufacturer of military vehicles. The rubber hatch seals that we supply resist over-compression and demonstrate the value that we add to defense contracts. For our 25 years, Elasto Proxy has been an important link in the military supply chain. Elasto Proxyalso holds a Controlled Good Certificate (CGC) and works closely with trade groups such as the Canadian Association of Defense and Security Industries (CADSI). (more…)

What’s the Right Rubber Tubing for Your Application?

Rubber TubingRubber tubing is used in fluid transport and for electrical protection. Applications include shock absorption and low compression force sealing. Different elastomers have different properties, so design engineers and technical buyers need to choose rubber tubes carefully. Specifications such as durometer (hardness) and inner and outer diameter are especially important to consider.

By choosing the right rubber compound for industrial tubing, you can strengthen your company’s product designs. You can also control costs by selecting rubber tubes that are cut-to-size and ready-to-install. Metal tubes resist high temperatures and provide physical strength, but they cost more than rubber tubes. Plus, metal tubing may be subject to rust, corrosion, or scaling. (more…)

Military Acoustic Thermal Insulation

Americans say “Zee” for the letter Z. Canadians say “Zed” instead. In both North American countries, their militaries say “Zulu” so that radio or telephone messages can be understood clearly. If you’re a defense contractor that makes military vehicles, it’s important to know you’ll receive exactly what you asked for. Elasto Proxy, a trusted member of the defense supply chain, can custom-fabricate thermal acoustic insulation that meets all of your requirements.

In this product overview, you’ll learn about two types of thermal acoustic insulation – each with part numbers that begin with Z. So whether you say Zee, Zed, or Zulu, you can count on Elasto Proxy’s U.S. and Canadian offices to support the mission every time. (more…)

Armored Vehicle Gaskets

Armored vehicles play an essential role in projecting military power and protecting  service personnel. Metal plating and weapons systems are what most observers notice, but closer inspection reveals that rubber parts also help support the mission. In this technical article from Elasto Proxy, you’ll learn about the six types of custom-fabricated components that we supply for a military vehicle that’s been an important part of U.S. and Coalition operations in Iraq and Afghanistan.

How to Choose Bulb Trim Seals

Bulb Trim SealsBulb trim seals provide sealing and insulation for doors, hatches, and enclosures. These industrial rubber products have bulb and retainer sections that are made of different materials. The bulb section provides sealing and insulation under compressive force. The trim or retainer presses onto a flange or substrate.  Each section of the seal also has a different durometer or hardness to support proper compression.

This technical article from Elasto Proxy is designed to help you choose the right bulb trim seals for your application. In addition to compound selection and part dimensions, product designers and technical buyers need to consider color, texture, internal supports, and exterior finishes. Your application may also require flame-resistant compounds or rubber that meets specific industry standards. (more…)

Military Vehicle Insulation

Military Vehicles

Thermal acoustic insulation is used in the floors, doors, side panels, and engine bays of military vehicles. Many different types of insulating materials are available, but you don’t need to be a material scientist to make the right choice. By choosing an experienced custom-fabricator who provides design assistance and help with material selection, you can strengthen your product designs as well as your supply chain. That’s why the North American defense industry asks Elasto Proxy for thermal acoustic solutions. (more…)

Silicone Hatch Seals Resist Compression and Temperature

Silicone Hatch Seals | ST-375-23-SM
Silicone Sponge ST-375-23-SM

Elasto Proxy custom-fabricates silicone hatch seals for demanding applications. These specialty gaskets support superior sealing with good compression set and temperature resistance.

Gasket designers want rubber hatch seals that are as tough as the vehicles, equipment, and infrastructure that need them. If a hatch seal can’t withstand compression, it may over-compress and admit wind, water, dirt, or mud. If a hatch seal can’t withstand a wide range of temperatures and outdoor environmental conditions, seal failure can result, too. If you need hatch seals for military vehicles, mobile equipment, marine applications, or HVAC systems, there’s plenty to think about. Fortunately, help is available.

For every hatch seal design, compound selection is critical. As readers of this blog learned last March, choosing the right rubber won’t stop enemy fire, but choosing the wrong rubber can result in over-compressed hatch seals on military vehicles. That’s why although neoprene rubber offers an excellent balance of material properties, this elastomer wasn’t the best choice for the military gaskets that Elasto Proxy inspected. After examining the results of over-compression, we recommended silicone sponge rubber seals instead. Is this same elastomer right for your application, too? (more…)

Military Vehicle Gasket Materials

Have you ever wondered why the military uses so many acronyms? It’s because soldiers, sailors, airmen, and marines need to convey information quickly, accurately, and efficiently. That’s why suppliers to the defense industry are also more likely to hear a term such as “MRAP” than the phrase “mine-resistant ambush-protected vehicle”.  For defense contractors who want to win new business, mastering these acronyms can be like learning a new language.

Like any specialized discipline, gasket design has its own language, too. For example, many rubber gaskets are made of synthetic elastomers with names such as Buna-N and EPDM. Published specifications such as ASTM D2000 use letters and numbers to “call out” the properties of vulcanized rubber in a highly-structured way. Units of measure such as durometer (hardness) are sometimes unfamiliar, so buyers and designers may need assistance in order to translate the language of rubber into project specifications. That’s just part of how Elasto Proxy can help. (more…)
