• Standard formula– Black appearance– 20 min. of working life– 180 min. to pressure test

• Quick-set formula in development

• Simple, low-cost applicator

• NSF approvedMUELLER INDUSTRIES, INC. - CONFIDENTIAL

Engineered Seals

• High-chlorination resistant (inc. chloramines)

• One-way “lip-seal” design– Easy insertion - Compensates for eccentricity– Strong seal - Resists cuts

• 63% more surface contact than o-rings

EngineeredSeal

Valve Partnership

• Sold by Apollo Valves (Conbraco)

• Utilize identical design and seal

• Currently:– ½ - 2” Bronze ball valve– 77 Series

Installation Steps

• Step 1 - After cutting and deburring tube, clean tube surface with an alcohol wipe.

• Step 2 - Mark tube to depth of insertion plus ½”.• Step 3 - Place a small ribbon of adhesive around

the tube and, above 1”, inside the fitting.• Step 4 - Push fitting on the tube, making a ¼-turn

motion, forcing a bead of excess adhesive out of the joint.

• Step 5 - Position fitting as needed. Then, allow joint to cure prior to pressure testing.

Top 10 Reasons to use an Adhesive Fitting

System

10. Allows repositioning of fittings during installation

9. Seals tube imperfections that conventional O-rings alone cannot

8. Integrates primary and secondary sealing mechanisms

7. Adhesive developed in partnership with 3M Corporation

6. Installs with no electricity, gas, or VOCs...environmentally friendly

5. Joining is fast and intuitive – little training required

4. Offers superior performance to press, push, CPVC, and PEX

3. Uses reliable, lightweight, inexpensive wrot copper fittings

2. Does not require expensive, cumbersome tools for installation

1. Offers lowest installed cost of a copper plumbing systemMUELLER INDUSTRIES, INC. - CONFIDENTIAL
