FAQ

Can this adapter be used with potable water?

The adapter is not intended for potable water distribution. Brass alloys used in this product can contain trace amounts of lead, which may leach into drinking water and exceed regulatory limits for safe consumption. While the material offers excellent corrosion resistance for many industrial fluids, health‑safety standards for drinking water require lead‑free certifications that this fitting does not possess. For applications involving drinking water, we recommend selecting a certified lead‑free stainless‑steel or certified brass fitting that explicitly states compliance with NSF/ANSI 61 or equivalent standards. Using the FloFlex adapter in non‑potable water, air, vacuum, or steam systems ensures reliable performance without compromising water quality.

What sealant should I use with this adapter?

For optimal leak protection, apply a compatible pipe sealant or PTFE (Teflon) tape to the male BSPT threads before installation. A high‑quality PTFE tape, typically 3‑4 wraps, provides a reliable barrier that fills thread gaps and accommodates thermal expansion. If a liquid sealant is preferred, choose a non‑metallic, petroleum‑resistant compound rated for the operating temperature range of –65 °F to 250 °F and pressure up to 250 psi. Ensure the sealant is compatible with the fluid being conveyed—oil‑based sealants for hydraulic oil, water‑based sealants for non‑potable water, and steam‑grade sealants for steam applications. After applying the sealant, tighten the adapter by hand until snug, then give an additional quarter turn with a wrench to achieve a secure, leak‑free joint.

What is the maximum operating pressure and temperature?

The adapter is engineered to handle a maximum operating pressure of 250 psi, which covers the majority of standard hydraulic, pneumatic, and low‑pressure steam applications. Its temperature tolerance spans from –65 °F at the low end, suitable for cryogenic or refrigerated environments, up to 250 °F on the high end, allowing use with hot water, steam, and high‑temperature air streams. When operating near these limits, it is important to verify that the connected system components are also rated for the same pressure and temperature conditions to maintain overall system integrity and safety.

Is this adapter compatible with stainless steel or copper pipes?

The brass construction of the adapter is compatible with a wide range of pipe materials, including stainless steel, copper, bronze, aluminum, and iron. When connecting to stainless steel or copper tubing, ensure that the mating NPT or BSPT fittings are properly prepared with the appropriate sealant to prevent galvanic corrosion. Although brass and stainless steel have different electrochemical potentials, the use of a suitable sealant and occasional inspection will mitigate corrosion risks. For copper connections, the same sealing practices apply, and the adapter’s corrosion‑resistant properties help maintain a durable joint.

How do I install the adapter correctly?

Begin by cleaning both the BSPT male threads on the adapter and the NPT female threads on the receiving fitting to remove any debris or old sealant. Apply PTFE tape or a compatible pipe sealant to the male BSPT threads, wrapping the tape clockwise around the threads for three to four turns. Insert the male end into the NPT female fitting and turn it by hand until it is snug. Using a wrench, give an additional quarter‑turn to ensure a tight, leak‑free seal. After installation, inspect the joint for any gaps and test the system under pressure to confirm there are no leaks.
