Need a longer stainless steel nipple?


Note: Do not use thread sealing tape or pipe dope on threads when connecting these flexes.
Water flex connectors with FIPS nuts come with EDPM rubber washers used to seal against the end of the pipe.
Thread sealant can prevent the female nut from tightening all the way causing the washer not to seal.



Term Definitions for Fittings
  • O.D.: Outer Diameter - if threaded, fit compression fittings
  • I.D.: Inner Diameter
  • S.J.: "Slip Joint" - most common 1/2" female pipe threads -non tapered
  • Washing Machine: Standard 3/4" female hose threads
  • FHT: Female hose threads (think garden hose)
  • FIPS: Female iron pipe size threads on the inside of fitting
  • MIP: Male pipe threads on the outside of fitting
  • W.C.: Female threads that fit toilet fill valves
  • PTC: John Guest push to connect - fits onto nominal copper pipe
  • CTS: Copper tube Size

Frequently Asked Questions

Q. "I'd like longer stainless flexes than you show. Are they available?"
A. You can easily connect these stainless steel flexes together by using brass or stainless steel regular "close" nipples, which can be purchased here. Be sure not to use any Teflon(PTFE) thread sealing tape or pipe dope when connecting two flexes using these fittings. Water flex connectors with FIPS nuts come with EDPM rubber washers used to seal against the end of the pipe. Thread sealant can prevent the female nut from tightening all the way causing the washer not to seal.

Q. "I'm used to using copper connectors on my water heater. Are the 3/4" Fips Stainless connectors as good?"
A. Most water heaters are steel. Stainless steel is a far better metal to use between copper, galvanized or non-metal piping and a steel tank. Yes, the above 3/4" Stainless connectors are designed for water heaters and, we think that once you have used our deluxe full-flow, corrugated stainless water heater connectors you won't want to go back to using copper ones. Easy to install, durable and the prices aren't much different than the old type of copper flexes.

Q. "Do you offer volume discounts on these?"
A. On an order of 10, 25 or 50 of the same item we offer an discount pricing. Volume pricing will appear in your shopping cart.

Q. "I need 100 of one size, how is your inventory on these stainless flexes?"
A. On all but the commercial flexes it is rare that we can't fill orders 100%. If you need 100 of a 1 1/2" commercial stainless flex we might not be able to fill the entire order immediately. Baring unforeseen circumstances, we can get them quickly.

Q. "What about electrolysis and stainless steel?"
A. Using stainless steel connectors can be somewhat helpful. Stainless (like brass) is an alloy metal. The electrical characteristics of alloys seem to make them a bit less prone to dielectric action than pure metals such as copper or iron. The more non-corrosive the alloy components (stainless for example has nickel - a very non corrosive metal) and the wider the electrical potentials of the components of the alloy, the less dielectric problem there seems to be. The alloy materials don't prevent the results of dielectric action, they just spread it over a greater area. There is less corrosion build up at the point of connection using stainless steel, than is seen when a copper adapter fitting is attached to a galvanized nipple or fitting.

Q. "What are the pressure ratings on these?"
A. The corrugated stainless steel flexes offered on this page have a 200psi working pressure, well in excess of the maximum building water pressure allowed by most codes, which is 80psi. These are all top quality flexible connectors.

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.
