Product review (5 stars): Exact replacement part, good quality.
Excellent replacement for the original.  However, I discovered after receiving that I could have just bought a water line coupler with thesame type/size fittings and taken the o-rings out of it to replace my worn ones.  Total cost would have been around 5 dollars.  My original housing was otherwise undamaged.  Does not affect the rating of the replacement housing, which is a perfect replacement, but might be useful info for someone else in my situation.
