TechnaLoc® Bonded Seals

Greene Tweed’s TechnaLoc® elastomeric bonded  seals are made of elastomers bonded to flat  components composed of coated aluminum,  stainless steel, or titanium. 

Our proprietary elastomer materials ensure high  durability and sealability over the lifetime of an  aircraft, and can bond to stainless steel and  aluminum substrates. We offer options for Chemraz® FFKM and Fusion™ FKM as well as other materials. 

Based on application requirements, elastomers used  in TechnaLoc® seals can be bonded using either  adhesive or mechanical methods. The proprietary  elastomers used in TechnaLoc® seals have an  industry-proven broad temperature range and fluid  compatibility, making them suitable for many critical  aerospace applications.

In addition, TechnaLoc® products have been ideally  matched to bonding technology to ensure the seal  bonding strength meets and exceeds industry standards. 

Greene Tweed’s durable, reliable TechnaLoc® bonded seals can be custom-designed to meet  customers’ unique needs, as a result of our advanced  engineering and development resources.  Our proprietary materials, along with our manufacturing  quality, on time delivery, and prototyping, are supported  by application engineers for best design and fit.  

We test our TechnaLoc® seals in real application  environments, and test custom-designed bonded seals  in-house prior to customer delivery for qualification.

Features and Benefits 

•Reduced assembly time and complexity •Reduced component count •If replacing RTV (room temperature vulcanizing)  static sealing, less likely to cause leakage due  to poor installation  •Can be disassembled without expensive  cleaning process

Application Examples 

•Engines – fuel application and lubrication systems • Gearboxes •Utilities – hydraulic •Flight actuation – hydraulic •Landing gear – high pressure • Ground vehicle suspension
