my 100mtr microbore from gardiners is connected in the same way, microbore connected to 13mm pipe via a reducer , then on to brass elbow on reel,
now problems after 2 1/2 years , turned it around last week , as good as new,
tip,
after prolonged use turn it round , as on mine to first 30mtrs or so , took the most wear, by turning round you increase it's life
