    • MIPS: Threads on the outside of fitting
    • Barb: Barbed fitting
    • PSI: Pound-force per Square Inch

    The following chart will help you determine the length of "close" nipples based on the pipe size:
    Pipe Size 1/8" 1/4" 3/8" 1/2" 3/4" 1" 1 1/4" 1 1/2" 2" 2 1/2" 3" 4"

    Example: if the pipe size is 1" then the close length is 1 1/2"

    Frequently Asked Questions

    Q. "Do you sell stainless flare, compression fittings or stainless tubing?"
    A. We also offer stainless water flexes, stainless gas flexes, and stainless hose clamps. But what we show above is all that we sell in the way of stainless fittings, and we don't sell tubing. We do sell brass flare and compression fittings.

    Q. "Are half couplers / couplings threaded all the way through the inside of each fitting?"
    A. No, half couplers have tapered female threads, therefore, do not have threads throughout the entire inside portion of each fitting.

    Q. "What is the pressure rating for your stainless steel fittings and nipples?"
    A. Both type 304 and type 316 fittings and nipples have a normal working pressure rating of 150 psi.

    Q. "Will IPS-sized fittings work with NPT pipe thread?"
    A. Yes. Many companies and individuals use the abbreviation IPS which normally refers to iron pipe size. When we use the term 'IPS-sized', or either male (Mips) or female (Fips), we are refering to pipes with NPT threads. NPT is the abbreviation for National Pipe Thread Tapered which is the thread standard used in the United States for galvanized, black, brass, stainless steel, PVC, ABS or other materials to connect pipes and fittings in plumbing. We offer more detailed information about NPT pipe threads here.

    Q. "I'm hearing a lot about lead-free these days. What does that have to do with plumbing products and how does the new lead-free legislation affect me?"
    A. Basically, the laws implemented Jan. 1st, 2014 require plumbing products that come in contact with drinking water to be essentially lead free (less than 0.25% weighted average). For further information about how the law determines what is lead free, rules regarding which plumbing products must be lead free, and who these laws will affect, please visit our LEAD FREE Plumbing Information page.
