I purchased the 4-Inch Diameter x 10-Foot Length Light-Duty Semi-Clear Dust Collection Hose from Woodcraft so I could connect the G0513X2. I picked it up at the store (did not want to wait a week for hose from Grixzzy).
The web site lists these benefits:
Economical hose solution for central and portable dust collection systems
Cost is double that of the Grizzly hose. I purchased it because of timing not price.
Translucent material makes it easier to spot a blockage vs. standard black hose
Difficult to see thru but they may be right.
Light weight polyethylene hose reinforced with an external polypropylene helix
The hose is easy to tear (see comments on installing below).
Smooth interior assures minimal friction loss and efficient air flow
This is probably true - the interior is much smoother than what I normally use.
The problem:
Getting the hose onto a fitting is a royal pain. I managed to break several fingernails and tore the hose a couple of times installing it. Most connections I only managed to get a small part of the hose on the fitting - not enough to clamp. I initially thought it was because I was using fittings from Grizzly - I had purchased a blast gate at the same time from Woodcraft and the fit was just as poor on that fitting. Same problem on the ports on the G0513X2 - almost impossible to get it on. Since I had cut the hose into the pieces I needed so returning it is not an option.
Bottom line is that I would not reccommend this hose to anyone thinking about getting it.
I ended up ordering 20 ft of 4" hose from Grizzly for the same price as the 10 ft from Woodcraft.
