Thread Sealants for NPT threads

National Pipe Threads (NPT) as specified by the American National Standards Institute (ANSI) have tapered threads. These are the most common threads used for residential plumbing and general purposes. NPT threads are used for sealing and joining pipe to fittings in low pressure liquid, air, and mechanical applications. Tapered threads are deeper at the end of the pipe and become increasingly shallower the further they are from the end of the pipe. The tapered thread pitch is 3/4" over one foot of length which is the same as 1/16 of an inch in an inch. The taper on the pipe allows the pipe to screw inside the fitting only until it is forced to stop because of the taper. The distance the pipe can actually be threaded into the fitting is specified by the ANSI standard. After tightening a pipe into a fitting with a wrench the threads may have slight air spaces between the pipe and fitting which could cause a leak and therefore a pipe sealant must be used to ensure all gaps are filled to prevent leakage.

Dry-seal threads (NPTF) also are tapered threads. NPTF threads are used in applications where pipe sealing compounds could fail due to higher heat or pressure applications than normal NPT threads can withstand. NPTF dry-seal threads are designed to seal mechanically by slightly, but sufficiently, crushing the threads into a fitting when tightened with a wrench. This allows the joining of the pipe and fitting without a sealant.

NPT and NPTF threads are interchangeable with proper pipe joint compound sealants or PTFE tape. None of the other thread standards are interchangeable. Female NPT threads are sometimes designated as "FPT" or "Fips" and male NPT threads as "MPT" or "Mips"

Frequently Asked Questions

Q. "Can I get longer lead free brass pipe nipples than what you list above?"
A. We are currently showing all of the lead free brass nipple lengths available. As longer lengths become available we will add them to our pages, however, due to shipping costs 48" lengths are the longest we will ship.

Q. "What is PTFE tape, and why do you not offer Teflon^® tape?"
A. PTFE is the abbreviation for the chemical composition poly-tetra-fluoro-ethylene. PTFE is a heat resistant, non-sticking, chemical and corrosion resistant film cut into these widths and lengths for the purpose of sealing pipe threads. The natural color of PTFE is white but it can be pigmented to put color into it. Many companies make PTFE tape. Teflon^® is a brand name for PTFE that is owned by the DuPont™ company. We just don't happen to offer their brand name.

Q. "What is brass made of and why are these brass fittings considered lead-free?"
A. Brass is made with a mixture of metal alloys of mostly copper and zinc and also small amounts of other metal alloys like lead, tin, manganese, nickel, aluminum or iron. The mixtures of these alloys determines the type of brass it is made into and for what purpose it will be used for. Usually brass fittings used for potable water have approximately 62-65% copper, 30-35% zinc and small percentages of tin and lead. On January 1, 2010, laws went into effect in California, Maryland, and Vermont, and on January 1, 2013 in Louisiana, that lead-free materials must be used for every component that comes into contact with drinking water. These laws (California AB 1953, Vermont VT S.152, and Maryland HB 372) reduced the allowable lead content (weighted average) in brass from 4% to 0.25% lead. To be considered lead free, brass fittings must have 0.25%, or less, lead content.

Q. "What does it mean to have ANSI Certification for lead free plumbing products?"
A. Laws requiring plumbing products that come in to contact with drinking water to be essentially lead-free (0.25% weighted average) have been passed in California, Louisiana, Maryland, and Vermont. In order for companies to ship these plumbing products to locations in CA, LA, MD and VT, they must be ANSI certified lead free.

Q. "What is CA AB 1953, LA Act No. 362, MD HB 372, and VT S.152 and how is this different from previous low-lead legislation?"
A. The United States Environmental Protection Agency (EPA) regulates the amount of lead in drinking water under guidelines established in the Federal Safe Drinking Water Act (passed in 1974; amended in 1988 and 1996). This Act defines "lead-free" as not more than 8% lead in pipes and fixture fittings. PLEASE NOTE: Use of the term "lead-free" varies between the new legislation in CA (AB 1953), LA ( Act No. 362), MD (HB 372), and VT (S.152), and in the current Federal Safe Drinking Water Act requirements. In the new legislation for CA, LA, MD and VT only (as of Jan 2013), it will mean 0.25% or less (weighted average). Similar national legislation is scheduled to go into effect Jan 2014.
