Q. "I have heard of National Pipe Threads (NPT) but what does 'Thread UNS' mean?"
A. UNS stands for "Unified National Special" threads. The 7/16" x 24 threads on this fitting are a special 1/4" od compression female thread, (same female thread as a brass compression nut). This special fitting is used to attach directly to the male inlet threading on filter faucets that have 1/4" compression inlets.
Q. "What are the locking clips used for?"
A. The locking clips are used for extra protection when a Quick Connect Push-In fitting is used excessively and the tubing is removed and reinserted a lot. The locking clips are to be inserted directly behind the collet.
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.
