I wouldn't recommend not using a washer, but the fiber washer available at your supplier will be fine, I've used them before with no problems (they are a one time use item though in any case), in fact, I've even used the cheapo fiber washers for garden hoses before no problems.
If it's not leaking now though, I wouldn't call it an emergency to replace it, but you won't get away with for long since eventually the mating surfaces won't seal I would assume. |
