Fluid Transfer Seals Drums

In the Automotive and Semiconductor industries, fluid transfer seals play a vital role in directing high-pressure fluids through intricate systems. The effectiveness of these seals is essential for successful applications, hinging on their robustness and endurance.

For uninterrupted fluid flow devoid of leaks or interruptions, these seals must possess the optimal dimensions, configuration, and material.

Key Attributes

Fluid Transfer Seals are integral in numerous automotive functions. Particularly, automatic transmissions rely on these seals to guide intricate fluid circuits that supply oil and engage hydraulic clutches. Whenever fluid shifts within a vehicle, these seals ensure the swiftest and most effective route.

Additional pivotal automotive uses encompass:

  • Pressurised air intakes.
  • Coolant passages.
  • Fuel and lube oil supply and return lines.
  • Crossover pipes.
  • EGR passages.
  • Transmission fluid ports.

Fluid Transfer Seals Features

  • Self-retaining, pressure-energised.
  • High compliance; “clusters” merge multiple seals into one.
  • Compact, space-efficient designs.
  • Low compression force; tailored to your needs.
  • Various rubber compounds and inserts for application compatibility.

Prevents Operational Failure

Central to every sealing solution is the prevention of leaks. Regardless of the context, when a seal degrades and leak paths emerge, its functionality diminishes, posing the risk of system failure. Such failure can result in severe system damage, leading to permanent harm and shutdowns.

Fluid transfer seals hold the crucial task of sealing potential leak paths, ensuring steadfast sealing performance in all applications. In the automotive realm, these seals play an intensified role in facilitating smooth and efficient fluid movement across various systems. The robustness and endurance of these seals are indispensable for the functionality of automotive operations, and their benefits continue.

Fluid Transfer Seals Benefits

  • Swift, foolproof assembly for single/multiple ports.
  • Adapts to component variation and misalignment.
  • Contains pressurised fluids, even across gaps.
  • Saves space, trims inventory, and part numbers.
  • Cuts rework, warranty costs, and tool access needs.
  • Boosts reliability, longevity, and design flexibility.

Shapes and Sizes

Certain applications necessitate a single seal that operates effectively across gaps, from slight to millimeters. Others require sealing multiple ports onto a misaligned surface or accommodating an offset tube. These diverse scenarios, whether involving pressurised fluids or not, all share the common need for a customised seal to optimise system performance and cost.

A pivotal aspect in many cases is the seal’s self-retention capability. The chosen approach, either rubber or metal press-fit, balances retention and assembly ease. These self-retained seals enable inverted assembly, secure shipment, and resistance to blowouts under high pressure. Appropriately designed, self-retained seals prevent loss or damage, curbing expensive rework and warranty concerns.

Types of Fluid Transfer Seals

  • Transfer Port Seals.
  • Long Lip Seals.
  • Cluster Seals.
  • Press-Fit Pipe Seals.
  • Easy Assembly Pipe Seals.
  • Flangeless Pipe Seals.

Fluid Transfer Seal Materials

M Barnwell Services has access to an extensive compound library, many of which are approved to OEM and independent lab standards. When unique applications arise, our industry-leading compound development aids swift market entry, backed by robust testing.

Fluid Transfer Seals are most commonly made from Silicone (VMQ) due to their remarkable versatility in a multitude of applications across diverse industries. In fluid transfer, it’s valued for its exceptional temperature resistance and minimal compression set. These traits maintain seal flexibility, effectively sealing against leaks.

Silicone can be tailored precisely to meet automotive demands, accommodating intricate forms, various sizes, and standard colors. As a dependable and secure choice, silicone offers reliable fluid transfer sealing solutions.

However, our seal division employs a number of other top-tier polymers like Nitrile (NBR), Hydrogenated Nitrile (HNBR), Ethylene Propylene (EPDM), Fluorosilicone (FVMQ), Ethylene Acrylic, Polyacrylate (ACM), and Fluorocarbon Elastomers. Diverse insert materials are available, from common plated steels to advanced composites.
