Lead-Free FAQ: Materials, Installation, Standards
ProBite® fittings are certified up to 200 PSI
ProBite® Lead-Free Product Materials
Q: What materials are present in ProBite® Lead-Free products and do you manufacture compliant brass fittings?
A: 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 also manufacture a complete line of AB1953, lead law compliant Brass push fittings, and unlike our competitors, ProBite® utilizes an integrated brass o-ring guide that allows for full flow without plastic inserts.
How To Connect Tubes/Pipes
Q: Do ends connect the same way a solder joint connects?
A: Yes. Just like sweat copper fittings, tube ends should be chamfered, de-burred and reamed. These steps are essential to 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.
Q: Can PROBite® fittings be connected to copper?
A: Yes, as well as CPVC and PEX tubing. When connecting to PEX tubing, a tubing insert stiffener is required.
System Installation & Maintenance
Q: Can a PROBite® fitting blow off a water system?
A: NO, the grip ring technology utilizes an opposing force principle, which simply put, the higher the force used to pull the fitting, the deeper the fitting bites into the tubing.
Q: How much pull force and to what temperatures have PROBite® fittings been tested?
A: PROBite® fittings are factory tested to over 900 PSI force and temperatures of 200 °F. View ProBite® Certifications.
Q: What support hanger spacing must I use with my PROBite® System?
A: Support is identical to a sweat system and should adhere to local codes. Always fully support heavy loads on your plumbing system.
Q: How do I test my ProBite® System?
A: 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 the
local plumbing regulations.
Q: Do I need to lubricate the joint when installing?
A: No, ProBite®’s seals are factory-lubricated with an NSF-61 approved lubricant.
Q: Do I still have to flush my system?
A: Yes, but the system 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.
How To Adapt 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
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?
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 ProBite® push-to-connect fittings be rotated?
A: ProBite® fittings can be rotated 360 degrees (as long as the system is not under pressure).
Q: Do ProBite® products work with water charged system?
A: Absolutely. ProBite® fittings can be easily installed on wet or dry applications as long as the system is depressurized prior to installation.
Q:Are ProBite® connection fittings reusable?
A: ProBite® quick connection fittings can be simply removed and reused as long the o-ring seal is in-tact.
