Boshart FGL00701 – Frequently Asked Questions

1) How much clearance do I need for a Boshart 3/8 inch locknut in a tight enclosure?
Plan on roughly 0.850 inches across the nut and 0.300 inches of height. That height is what you need between the enclosure wall and whatever sits behind it, and the 0.850 inch across-flats dimension tells you whether a wrench or channel locks will actually get on it in a crowded box.
2) Is a galvanized steel locknut OK behind the wall where things stay damp?
Yes. The Boshart FGL00 locknut is galvanized steel, and that zinc coating is what makes it suitable for behind-the-wall and under-floor rough-in where moisture is a fact of life. It is the same material family as galvanized steel and iron pipe, so you are not mixing dissimilar metals at the joint.
3) What does a plumbing locknut actually do on a rough-in connection?
It mechanically clamps a threaded nipple or fitting to an enclosure, box, or fixture body. You pass the male thread through the hole and run the locknut up behind it, which holds the stub in position while you finish the assembly and keeps it from backing out afterward. On a 3/8 inch rough-in stub the FGL00 is doing that job without adding bulk to the joint.
4) Is the Boshart FGL00 locknut a sealing part, or do I still need to seal the joint?
It is a mechanical fastener, not a seal. The locknut holds the threaded connection in place; any watertightness comes from the pipe thread itself and whatever sealant or tape you use on it, or from a gasket or washer on the enclosure side. Specify those separately, since only the nut is supplied here.
5) Which Boshart FGL00 model numbers do I order from, and where are they made?
The FGL00 Series is ordered as model FGL00699 or model FGL00701. Country of origin is China. For MRO and stocking purposes, the series designation to standardize on is FGL00.
