1/4" heat shrink tubing is a good size for sealing larger solder connections like Deans Ultra connectors (with 12AWG or larger wire). It also fits snugly over servo connector housings and could be used to provide some strain relief near the connector (though the added bulk might prevent the connector from fitting in crowded receivers). 1/4" can fit up to 4 ribbons (3x conductors fused together) of 22AWG servo wire and will shrink tightly around as few as one ribbon.
This polyolefin heat shrink tubing starts to shrink at about 212°F, is rated for 275°F continuous operation, is split resistant, mechanically tough, and has a 2:1 shrink ratio. It is not crystal clear, but clear enough to read through and discern color codes for parts like resistors.
Please take note when ordering: All orders under 5ft will be supplied in 1ft lengths (so if you order 4ft you'll get 4 1ft pieces). Any quantity 5ft or greater will be custom cut to length. However, if you order 10ft, you will receive two 5 ft lengths.
