Little Joe Gas regulators covers allow venting of gas out of the port hole on side while keeping the cold in and the heat out.  Gas freezes to especially when it meets the summer heat.  PipeGlove’s Little Joe Regulators are sized to overlap the 1" nipples on lines coming in. Simply attach the 3 part cover by starting at the base, then wrap the nose securing the binding tightly around vent, and then connecting it all together with the back 360 cover of hook and loop. Our wraps are engineered to also cover heat trace and fit snug.
