Spears SPRN-2 – Frequently Asked Questions
1) What size and thread type is the Spears N-2 PVC transition nipple?
The Spears N-2 is a 3/8 inch x 1/2 inch transition nipple with male pipe thread (MPT) on both ends. The two ends are different sizes, so it steps a 3/8 inch threaded run up to a 1/2 inch threaded connection, or down the other way. Both ends thread into female sockets, couplings, or valve ports - it will not solvent weld.
2) Can I use a PVC transition nipple to connect to a metal threaded fitting?
Mechanically yes - the N-2 has standard NPT male threads on both ends, so it mates with any female NPT port, metal or plastic. Two cautions with a PVC male thread into metal: thread sealant tape or paste only, never pipe dope not rated for plastic, and hand tighten plus one to two turns with a wrench. PVC male threads are the weak point in a plastic-to-metal joint and over-torquing splits the nipple. Note the body is PVC, not CPVC, so it is not for hot water lines.
3) Will a Spears PVC transition nipple work on a hot water line?
No. The N-2 is PVC, which is a cold water and cold process material. For hot water you need the CPVC equivalent. Using PVC on a hot line softens the body and the threaded joint is the first thing to fail.
4) Should I use a PVC nipple or a brass nipple for a 3/8 to 1/2 inch threaded transition?
PVC is the choice where corrosion or chemical attack would eat brass - irrigation, drain and chemical lines, cold water service. It is also far lighter to handle. Brass or galvanized steel is the right call where the joint carries mechanical load, sees hot water, or gets wrenched on repeatedly, because a PVC male thread has less strength than a metal one. The Spears N-2 is the PVC option in a 3/8 x 1/2 configuration.
5) Do I need anything else to install a 3/8 x 1/2 PVC transition nipple?
Just thread sealant. The N-2 is threaded on both ends, so there is no primer or solvent cement involved - use PTFE tape or a thread sealant compatible with plastic threads on each male end and thread it into the two female ports. No cement, no clamps, no gasket.
6) How many Spears N-2 nipples come in a pack?
The N-2 transition nipple is packed 100 per unit, so it is bought as a bulk stocking item rather than a single piece. That suits a plumbing contractor or distributor carrying 3/8 x 1/2 transitions as shelf stock rather than someone needing one fitting for one repair.
