The fittings are made of janky aluminum, so getting them tight enough to not leak is next to impossible without stripping them. YOU COULD ALMOST SNAP THEM LIKE A PENCIL! NO I didn't cross thread or any noob mistake like that. The aluminum is just weak. ALSO, the fittings that go through the body, should have a washer or or something to both compliment the fitment and provide rigidity which they don't. If you get this just be aware of the fact you'll more than likely be buying new fittings. Lines are great though.
