PRODUCTS

There are four different systems available to inflate OFF-THE-ROAD (OTR) tires, as follows:

LARGE BORE (LB)

Although identified as LARGE BORE, it does not really reflect the effectiveness when in use, as the actual bore is a mere 3/16?. However, when originally introduced, it did offer a significant improvement over the STANDARD bore products.

SUPER LARGE BORE (SLB)

Introduced in the early 1970, SUPER LARGE BORE featured a huge improvement in the required time to inflate a large tire. The bore was improved from 3/16? to just under 1/2?. It is still one of the most popular systems, primarily because of minimum clearance needed over the SUPER EXTRA LARGE and SUPER GIANT bores. It is also the most cost-effective system.

SUPER EXTRA LARGE BORE (SXL)

Introduced by EXACTRA in mid-1990's, it improved the bore to just under 5/8? thus reducing inflation time by as much as 50% over the SUPER LARGE BORE system. Since the variouscomponents are somewhat larger than those of the SUPER LARGE BORE, the application is limited to where there is sufficient clearance between the wheel/rim and the drive/ braking assembly.

SUPER GIANT BORE (SGB)

This system was introduced by EXACTRA during the last decade. It offers a similar fl ow as that of another product of same bore, but is more user friendly. The bore was improved from just under 5/8? for SUPER EXTRA LARGE to just under 3/4? allowing for a further reduction in inflation time by as much as 50% over the SUPER EXTRA-LARGE bore. Here the application is also restricted to vehicles that offer sufficient clearance between the wheel/rim and the drive/braking assembly.
