RLS LLC, manufacturer of the Rapid Locking System line of flame-free press-to-connect fittings for HVAC and refrigeration systems, announces that Milwaukee® Tool, in partnership with RLS, has introduced RLS-compatible jaws for use with its popular M18™ FORCE LOGIC™ Press Tools.

Available in sizes from 1/4″ – 1-3/8″, these new RLS ACR Press Jaws will allow M18 tool users to take advantage of the time-saving and safety benefits of flame-free RLS press connections for HVAC/R, without needing to invest in a new press tool. These are the industry’s first jaws approved to press RLS fittings using 32 kN (kilonewton) tools.

In addition, the new Milwaukee jaws are also compatible with a wide range of other 32 kN tools on the market, including those from manufacturers such as RIDGID, Klauke, Viega, Dewalt, NovoPress and Rothenberger. Contractors who already own any of these tools will only need to purchase the Milwaukee jaws to begin installing RLS fittings.

Milwaukee’s RLS-compatible jaws will be sold exclusively through Milwaukee distributors. Contact Milwaukee or visit milwaukeetool.com for details. For more information on RLS press fittings, and a complete RLS Tool & Jaw Compatibility Matrix, visit rapidlockingsystem.com.

About RLS Fittings

RLS press fittings connect in 10 seconds using a battery-powered tool and jaws, replacing the time-consuming process of manually brazing HVAC/R joints. The fittings result in faster, more consistent connections that reduce total installed costs, while also increasing jobsite safety by eliminating the use of an open flame. More than 10 million RLS fittings have been successfully installed since their introduction in 2015

Manufacturing Plant and Training Center in St. Louis, Missouri

RLS LLC, manufacturer of the Rapid Locking System line of flame-free press-to-connect fittings for HVAC and refrigeration systems, has announced it will be moving into a new 80,000 square foot multipurpose facility in St. Louis, Missouri, which will serve as its corporate headquarters and will include a state-of-the-art manufacturing plant, training center and showroom.

RLS will be relocating manufacturing from Shelbina, Missouri, where it has been sharing a plant with its sister company, Cerro Flow Products. Both are part of the Plumbing and Refrigeration sector of Marmon Holdings, a Berkshire Hathaway company. All RLS operations are planned to be consolidated into the new building by the end of 2021.

“We’re very excited to have manufacturing, office staff and training all under one roof,” said Paul Schubert, president of RLS. “The larger, upgraded facility will significantly increase our production capacity to meet the growing demand for our products. And the new training center will allow us to regularly educate HVAC/R contractors and distributors on our patented press technology, which is easily identified by our unique double circular press and flares.”

After originally introducing its press fittings in 2015 under the ZoomLock brand through a private-label agreement with Parker Hannifin, RLS has experienced tremendous growth since relaunching under its own brand name at the end of 2019. To support this continued growth, RLS has recently added more than 10 new positions in sales, marketing and engineering across the U.S., and is currently hiring.

“As more and more contractors discover the many benefits of using press fittings over the traditional brazing process, they continue to choose the time-tested and field-proven technology provided by RLS,” said Schubert. “As a result, we are continuing to invest in the facilities, equipment and people needed to meet demand.”

RLS press fittings connect in 10 seconds using a battery-powered tool and jaws, replacing the time-consuming process of manually brazing HVAC/R joints. The fittings result in faster, more consistent connections that reduces total installed costs, while also increasing jobsite safety by eliminating the use of an open flame.

There seems to be some confusion in the HVAC/R industry right now about press fittings. So RLS – manufacturer of the original RLS (Rapid Locking System) press fittings that were first sold under the ZoomLock brand name – wants to set the record straight.

While you can’t always trust what you hear, you can always trust the facts. And here are some undisputed facts about HVAC/R press fittings:

FACT: RLS is the inventor, patent holder and manufacturer of the original HVAC/R press fittings, which were introduced under the ZoomLock brand in 2015, through an exclusive agreement with Parker Hannifin Corporation’s Sporlan division. The fittings were designed and engineered – and continue to be made – in America.

FACT: The exclusive agreement ended in late 2019, and RLS stopped supplying fittings for ZoomLock in August of 2020. (See the official announcement here)

FACT: In August of 2020, Parker began selling press fittings manufactured in Europe by Conex Banninger (the Conex B MaxiPro line) under the “ZoomLock Max” name.

FACT: RLS now sells the exact same fittings, tools and jaws that were originally sold as ZoomLock under their own RLS brand name. That is why the original ZoomLock tools and jaws still work perfectly with RLS fittings – and always will.

FACT: Any rumors being circulated about RLS/ZoomLock jaws needing to be “traded in” or replaced are simply not true.

FACT: RLS fittings and jaws use a patented double circular press, with 360˚ metal-to-metal connections. ZoomLock Max/Conex B MaxiPro fittings and jaws use a hexagonal press similar to what is used in plumbing.

FACT: RLS fittings have a 6+ year proven track record of success worldwide. Conex Banninger introduced the new B MaxiPro design sometime after June of 2019.

FACT: The only difference between the original ZoomLock fittings and the current RLS fittings is the name. The product is identical – and made in the same American factory.

RLS Will Now Supply Its Patented Press Fittings Exclusively Under Its Own Brand

RLS® LLC (“RLS”) will no longer supply its patented press fittings to Parker Hannifin Corporation (“Parker”) for the ZoomLock™ brand. RLS is making this announcement to help avoid confusion in the marketplace as to the source and quality of fittings sold under the ZoomLock brand going forward.

RLS is a subsidiary of Marmon Holdings, Inc., a Berkshire Hathaway company. RLS designs, develops, and proudly manufactures in America its patented fittings engineered for high- pressure connections in the air conditioning and refrigeration industries. By replacing the time-consuming and demanding conventional practice of manually brazing copper joints, RLS’s fittings allow for faster, more consistent connections that reduce total installed cost while enhancing safety.

RLS introduced its patented fittings in 2015 and partnered exclusively with Parker at that time. RLS has since manufactured and supplied millions of fittings for Parker’s Sporlan Division to sell under the ZoomLock brand.

However, RLS recently decided not to renew its exclusive partnership with Parker. This decision was made, in part, because RLS believes discounted pricing provided to Parker was not passed along to customers as intended. Paul Schubert, President of RLS LLC, said Parker has paid back most of the discounts at issue and RLS expects to fully recover the remaining funds.

RLS has also learned Parker plans to source fittings for its ZoomLock brand from Conex Universal Limited (“Conex”) in the United Kingdom.

RLS previously filed patent lawsuits against Conex in the United States and the United Kingdom alleging Conex infringed claims of RLS’s patents. RLS and Conex agreed to settle the lawsuits as reported here. As part of the settlement, Conex agreed, without admitting liability or infringement, that it would stop selling the design of its fitting that RLS accused of infringement in the lawsuits.

Today, RLS’s patented fittings remain the only complete range of refrigerant press fittings and are featured in the Copper Tube Handbook. They are also backed by a 10-year limited warranty and proven by millions of fittings installed.

“To be clear, RLS will no longer supply its patented, proven, and made in America product line to Parker to sell under the ZoomLock brand,” Schubert said. “To ensure end users are equipped with the high-quality product they need and have come to expect, look for RLS’s fittings under its own branding going forward. The RLS brand is your assurance of the same quality connection.”
