PROBite™ FAQ About Fittings, Valves & Controls


What are PRObite™ products made of?

The fittings are forged 36,500 Brass, as well a 69,300 Lead-free Brass(ASTM B-283), the gripping ring is made of a proprietary Stainless Steel, and the o-ring is EPDM pre-lubricated with an NSF-61 approved lubricant.

we manufacture a complete line of AB1953, lead-law-compliant brass push fittings and our brass o-ring guide does not use any plastic inserts, allowing for full flow.

How To Connect Tubes with PROBite™ Fittings

Connect tubes together the same way your would with sweat copper fittings. The tube must be chamfered, de-burred and reamed. It’s helpful to use an inner/outer reamer to properly prepare the tubes and ensure the proper connection of your PROBite™ push-to-connect fitting. Also, be sure to draw an insertion mark on the tube to indicate proper insertion of the tubing into the fitting.

PROBite™ connectors are ideal for use with Copper pipes, CPVC and PEX tubing. A stiffener is only required when connecting ProBite™ to PEX tubing.

How to Install, Test & Flush a PROBite™ System

A PROBite™ fitting can not blow of a water system because the grip ring technology utilizes an opposing force principle, which means that the higher the force used to pull the fitting, the deeper the fitting bites into the tubing.

PROBite™ fittings are factory tensile tested to over 900 PSI force and temperatures of 200 °F. Support hanger spacing is identical to a sweat system and should adhere to local codes, always fully supporting heavy loads on your plumbing system.

Pressure tests should be conducted the same way as you would with a copper sweat system. The system should be installed, pressurized and then held under pressure for a period determined by your local plumbing regulations.

Joints do not need to be lubricated because seals are factory-lubricated with an NSF-61 approved lubricant.

It is necessary to flush the system, but it will be cleaner and faster to flush since there is no solder or flux.

Q: Is testing of my PROBite™ System the same as testing a Copper system?

A: Yes, PROBite™ is tested the same way as a sweat Copper system.

Adapting Your PROBite™ System to Other Systems

Q: Are valves and specialty items available for my PROBite™ push-to-connect system?

A: Yes, please see our product catalog for more information.

Q: Can I use my own valves?

A: Yes, with two PROBite™ male threaded connectors.

Q: Can my PROBite™ system connect with existing threaded systems?

A: Yes, with the use of a PROBITE™ male threaded connector.

Q: Can I solder directly into a PROBite™ push-to-connect fitting or valve?

A: No, open flames should never be applied to the fitting or any surface within 10” of the installed connection.

Q: Should I use glue when installing PROBite™ fittings?

A: No, glues, adhesives or sealants are not required and should never be applied to the connection, fitting or tubing.

PROBite™ Standards and Approvals

Q: Is the PROBite™ system certified to NSF-61 standards?

A: Yes.

Q: What approvals does PROBITE™ have?

A: Manufactured by the world’s originator and largest producer of push-to-connect fittings, PROBite™ is certified to NSF-61. Additional certifications include: British: BS EN 1294/BS 864 Part 2: Copper and copper alloys: Copper fittings, British: WRAS approval, Netherlands: NF-EN 1254-1, German: DVGW GW 8.

PROBite™ System Design

Q: Are the “pressure drops” and “frictional loss” the same for a PROBite™ as well as Copper sweat systems?

A: PROBite™ fittings are full flow (unrestricted) fittings offering superior flow characteristics. The pressure drops and friction loss are similar to that of sweat copper fittings.

Q: Can I rotate my PROBite™ push-to-connect fittings?

A: Yes, the fittings can be rotated 360 degrees while the system is not under pressure.

Q: Can I install PROBite™ in a water charged system?

A: Yes. PROBite™ fittings install on wet or dry tube. However, you should always depressurize your system before installing PROBITE™ products.

Q: Can I re-use PROBite™ fittings?

A: Yes. Fittings may be removed and reused providing the o-ring seal has not been damaged.

PROBite™ Temperature and Pressure Ratings

Q: What working temperature/pressure is the PROBite™ System rated for?

A: 180 °F and 200 PSI. Typical plumbing systems operate between 40 – 90 PSI.
