Heavy-duty diesel | Trucking (OTR) | Marine
Parker has been a major supplier to the transportation and heavy-duty diesel market for over 60 years. Our portfolio of process technologies and product solutions are geared to driving value for OEMs.
We are an engineering company, which means we're constantly looking for innovative ways to:
- Extend equipment life
- Lower costs
- Simplify complex processes
- Eliminate multiple components through parts in assembly (PIA)
High Performance, Simplified Solutions
Our engineered static sealing solutions include resilient metal seals, composite bonded elastomeric gaskets, fittings and fastener seals.
Composite Bonded Solutions
Gask-O-Seals® are metal, plastic, or composite retainers with a machined groove in the retainer plate into which a custom engineered rubber element is molded. The elastomer seal may be mechanically and/or chemically bonded to create a dependable, responsive seal for flat or curved surfaces.
Edge-bonded Integral Seals™ eliminate the need for a machined groove in the mating sealing flanges. The seal is kept in place by mechanically and/or chemically bonding the elastomer to a frame edge that is separate from the flange.
Why choose rubber to metal bonded static gasket Integral Seal™ solutions?
- Easy to install because the sealing element is precisely and permanently molded in place
- Reduces hardware costs by eliminating need for machining groove in mating hardware
- Reduces warranty and re-work costs because by providing visual confirmation seal has been installed
- Rubber can be molded into bolt holds for positive pre-assembly gripping and transporting
- Permits reduced flange thickness, smaller bolts and bolt circle.
- Metal-to-metal contact eliminates retorquing
- Can be highly customized with features that aid automated assembly
Applications
- Engine block covers
- Gear housing to engine block
- Gear housing to oil pan
- Oil pan adapter gaskets
- Oil pump gaskets
- Oil coolant line bonded washers
- Transmission pan gasket
- Engine coolant line gaskets
- Stack valves
About the Integral Seal™
The Integral Seal is so named because it effectively integrates a stamped or machined metal or molded plastic retainer with a molded-in-place rubber sealing element to create an extremely versatile sealing device.
Versatile Sealing Device
The Integral Seal is custom designed, versatile and provides similar performance benefits seen with Parker's Gask-O-Seal®. The Integral Seal lends itself to space-constrained applications where overall seal thickness may be of primary concern.
Integral seals can be manufactured in thickness as low as 0.012".
Cost Competitive Option
Metal to metal contact of the seal to the mating surfaces establishes an alternate load path that assures positive closure and optimum bolt loading. Additionally, the Integral Seal's design lends itself to high volume manufacturing methods, including automated assembly, making it a cost-competitive option for high volume sealing applications
- Eliminates cost of machining grooves
- Reduces re-work costs because it can be visually inspected to verify proper assembly; offering the ultimate in qualit
Automation Friendly
Speed to Market
Use of bonded Integral Seal carrier gaskets allows you to build greater efficiency into assembly and automation. Speed to market and reduction of quality errors aren't just side benefits, they're profitability advantages for OEMs.
Global Trends & Electrification

One of the most significant global trends that will affect new commercial trucks and buses is emission standards.
To date, incremental technology is meeting vehicle efficiency regulations related to the Environmental Protection Agency's (EPA's) Greenhouse Gas emissions standards. However, new rules require further lowering of CO2 emissions and reductions to fuel consumption. Among a variety of technologies being considered by heavy-duty truck OEMs is:
- Some type of electric architecture to replace 12-volt systems
- Aerodynamic devices
- Lighter weight components
- Adoption of electrified vehicles
Electrification
Commercial Battery Powered Trucks
The U.S. transportation industry is rapidly evolving to meet the demand for clean energy. And for design engineers working at the forefront of truck electrification, this represents an opportunity to create a level of technology and performance that will move the country closer to decarbonization and a more sustainable future. But what are the barriers, motivators and strategies for accelerating the electric transition? What can engineers who are challenged with developing commercial battery electric vehicles do now to help?

What You Should Know About Advanced Bonding Technology
Bonded seals alleviate some of the most common issues encountered with strictly elastomer seals like and o-ring or press-in-place profile which has been installed in a machined groove.
When customers need enhanced performance or face challenges with common elastomer-only seals, they turn to advanced bonding technology solutions.
Case Study: Block-to-Liner Insert Seal
The Challenge: Industrial adhesive seal between pressed-in cylinder liner and engine block destablized under high temperature and vibration conditions resulting in component separation and coolant leakage.
