The Speardiver Aluminum Speargun Tube is a light stiff tube with 26mm inner diameter and 1.5mm wall thickness. Track height is 4.5mm above the inner diameter. These are the same high quality aluminum tubes used with Speardiver Phantom spearguns. Tubes comes with black anodized finish.

These tubes will fit most standard 26mm ID parts, and a wider range of handles and muzzles which may require a little filing down the peg to reduce its diameter, or shimming to increase it, for a good tight fit.

The tubes are not plugged, included with each tube are two compression rubber plugs which are used to seal it. All that's needed to install the plugs is an approximately 5/8" diameter rod to collapse the plug pushing at its center, thereby reducing its diameter and making it possible to slide it down the tube. If needed more rubber plugs are sold separately.
