Vavula para abastecer, efeito escala, no e caro comparado com outros sitios.nice quality good price...!!!Excellent fit and finish. I cant ask for more, it is built to perfection.
The cap screws down onto the brass fitting sealing it with a rubber which is under the cap.
I blew into the fitting to see if the seal was good ...it appears to be perfect....no chance of air getting into the system.
