If you’ve ever ordered a brass fitting and ended up with a leaking joint or a part that simply wouldn’t thread in, you already know the frustration. “NPT” appears on almost every fitting spec sheet, but most buyers don’t realize that knowing the term is only the starting point. Without confirming the full specification, you’re […]

A flashing ABS warning light while hauling a loaded trailer is never just a dashboard nuisance. In a heavy-duty fleet, it often means a safety system is offline, a roadside inspection is coming1, and a repair bill is guaranteed. When I talk to fleet managers and repair shops about this, many still treat the 7-way […]

Buyers of brass fittings from China often make decisions based on FOB unit price alone — and that approach regularly leads to cost surprises at the destination. Freight, duties, destination charges, and trade-term gaps can turn a “cheap” quotation into an expensive one. Understanding total landed cost is how you avoid that problem. Total landed […]

Long and short stroke brake chambers can look similar, and that creates a real problem when you need to order replacements quickly.

Every fleet manager dreads air leaks. They eat fuel, kill brake performance, and drain your wallet1. But are push-to-connect fittings really the weak link? No, push-to-connect fittings do not leak when you choose the right type, install them properly, and buy from a manufacturer who tests every single unit. At ROADSPOWER, our DOT-certified fittings pass […]

Do you still pick air brake tubing by color or price? That guess can cause brake failures and wasted inventory. Let’s clear this up quickly. Type A is non-reinforced air brake tubing, Type B is reinforced. But you cannot decide which to buy based on that alone. You must check the tubing marking, the installation […]
