Quality Tube Supply Ltd.

“L” Fin

Economically produced fin tube for moderate working temperature up to 150°C. “L” fins rely on maximum surface contact between fin and tube which is ensured by tension forming fin strip helically wound around the base tube. A considerable degree of protection is given to the tube by the foot at the base of the fin.
