Spears 8171-007 – Frequently Asked Questions

1) What sizes does the Spears 8171 PVC tank adapter come in?
The Spears 8171 tank adapter is offered in four trade sizes: 3/4 inch (8171-007), 1 inch (8171-010), 1-1/2 inch (8171-015), and 2 inch (8171-020). Size the adapter to the pipe run and the tank port you are tying into, since the socket end takes PVC pipe of that same nominal size and the threaded end is FPT at the same size.
2) How does a socket x FPT tank adapter connect on each side?
One end is a solvent weld socket, so PVC pipe slips into it and is cemented with primer and PVC solvent cement. The other end is female pipe thread, which takes a male threaded nipple or fitting. On the 8171 the body passes through the tank wall and the neoprene gasket seals against the tank surface as the nut is drawn up, so the joint seals on the gasket face rather than on the threads.
3) Can I use a PVC tank adapter on a chemical storage tank?
PVC body with a neoprene gasket, which is what the 8171 is built from, handles corrosion and many chemical services, and chemical and industrial tank installations are among its intended uses along with water storage, irrigation, and general plumbing. The deciding factor is the chemical itself: check the media against both PVC and neoprene, since the gasket is often the limiting material rather than the fitting body.
4) Do I need Teflon tape on the threaded side of a PVC tank adapter?
The FPT side of the 8171 is a tapered pipe thread joint and takes a thread sealant, commonly PTFE tape or a plastic-safe pipe dope. Hand tighten plus a turn or two with a strap wrench is enough. Over-torquing plastic female threads is the usual cause of a split hub, and the tank seal itself comes from the neoprene gasket, not from how hard you crank the threads.
5) What is the difference between a tank adapter and a bulkhead fitting?
A tank adapter like the Spears 8171 gives you a socket on one side and a female pipe thread on the other with a neoprene gasket at the tank wall, so it is the transition between PVC pipe and a tank port. A bulkhead fitting is what you install when you are cutting a new hole through a tank wall and need sealing surfaces on both faces. If you are piping into an existing tank port and want a cemented pipe connection on one side and a threaded connection on the other, the tank adapter is the part.
6) Will a Spears tank adapter work with Schedule 40 PVC pipe?
Yes. The 8171 is a PVC fitting carried under Spears PVC Schedule 40 fittings documentation, and its socket end accepts standard PVC pipe of the matching nominal size, 3/4, 1, 1-1/2, or 2 inch. Schedule 40 and Schedule 80 PVC share the same outside diameter at a given nominal size, so either will seat in the socket.
7) Which Spears part number do I order for a 2 inch tank connection?
Order 8171-020 for the 2 inch size. The series runs 8171-007 for 3/4 inch, 8171-010 for 1 inch, 8171-015 for 1-1/2 inch, and 8171-020 for 2 inch, all socket x FPT PVC with a neoprene gasket.
