Our line of Pencil end brushes are used on Magnetic Flux Leakage (MFL) pipeline inspection applications,
the revolutionary patent-pending manufacturing method offers the following advantages:

Mechanical attachment

No solder

No epoxy

No chemical adhesives

Minimal bristle loss (no furring)

Impervious to most chemical attacks, including Zinc Bromide

Infinite shelf life.

The brushes are sprayed with rust preventive and sealed in plastic

Nothing to deteriorate

All steel construction, not affected by high temperature and pressures

Any fill materials

Nickel plated wire and stainless steel wire do not solder well

Soldering and epoxy methods require cleaning procedures to remove oil and other contaminants, increasing the risk for a non-uniform bonding across the bristles

Fill material is available in: Carbon steel, Stainless steel, Nickel plated wire and Tin plated wire

High tensile failure point between

4400-4900 lbf
19500-21800 Newton

In the event of individual bristle loss, the structural integrity of the brush is not compromised, thus reducing the possibility of catastrophic failure

Excellent magnetic properties
B-H curve tests performed by the University of Pennsylvania showed that the standard deviation of the magnetic properties is about a third of the competitors solder pencil end brush
The brush size, bristle density, trim length and mounting plate geometry are customized to your specific
needs and tool characteristics. Virtually any brush pattern and brush angle could be achieved depending on your application.
