  1. Objectives • Offer a reliable, flameless joining system to reduce time and cost of joining copper tubing • Keep the professional tradesman’s preferred plumbing material, copper, relevant in a changing world • Provide a less costly flameless alternative to press and push type fittings MUELLER INDUSTRIES, INC. - CONFIDENTIAL

  2. Development Partners • Research – Leading University • Fittings – Mueller Industries • Adhesive – 3M Corporation • Seals – Minnesota Rubber • Valves – Conbraco MUELLER INDUSTRIES, INC. - CONFIDENTIAL

  3. Modern Adhesive Uses Carbon/HC Vertical & Horiz. Stabs. AF 163-2OST Kevlar/HC Vertical stab. Leading edge AF 163-2OST Comp/HC Fairings, Flaps AF 163-2K Comp/HC Ailerons AF 163-2XS Lightning Strike AF 163-2U Radome

  4. Adhesive Fittings • Currently: ½ - 2” offering....over 180 items • Soon: 2½ - 4” offering...over 250 items • Standard (solder) wall thickness • Made in USA with 75-years of experience • Rated for 250psi systems up to 180°F

  5. Fitting Notes • Stampings on each cup... One side: “ST” for StreamTECH Size notation Other side: “NSF-61” for potable water • Press tool will not fit elbows, tees, adapters, unions, or valves • No cast fittings (ex-drop ear ell) • Two-piece flange body MUELLER INDUSTRIES, INC. - CONFIDENTIAL

  6. Structural Adhesive • Two-part epoxy • Standard formula • Black appearance • 20 min. of working life • 180 min. to pressure test • Quick-set formula in development • Simple, low-cost applicator • NSF approved MUELLER INDUSTRIES, INC. - CONFIDENTIAL

  7. Engineered Seal 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

  8. Valve Partnership • Sold by Apollo Valves (Conbraco) • Utilize identical design and seal • Currently: • ½ - 2” Bronze ball valve • 77 Series

  9. 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.

  10. Top 10 Reasons to use an Adhesive Fitting System • 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 system MUELLER INDUSTRIES, INC. - CONFIDENTIAL

  11. Tension (PULL) Test Determines shear-force capacity of assembly

  12. Hydrostatic pressure Test Determines static pressure capability at 72° & 180°F

  13. Hydraulic Shock Test Subjects assembly to 10,000 cycles of water hammer

  14. Vibration Test Subjects assembly to 1 million cycles vibration

  15. Thermocycling Test Takes ½” & 2” systems from 72° to 180°F for 7000 cycles

  16. Third-Party Listings • NSF listing for potable water..............½ - 4” • IAPMO “Classified” listing..................½ - 4” • IAPMO Standard.................IGC 251-08 • ICC-ES PMG listing...........................½ - 4” • ICC Listing Criteria....................LC1020

  17. Marketing Approach • Current Focus • Commercial Plumbing • Mechanical / HVAC / Process Piping • Future Opportunities • Refrigeration • Natural Gas • Medical Gases MUELLER INDUSTRIES, INC. - CONFIDENTIAL

  18. Production Installations • Air & water piping extensions installed by a mechanical contractor outside of Memphis • 500 feet of 2” tube with ¾” drops on 40-foot centers • Two guys put in the necessary supports and completed the installation in less than 16 man hours MUELLER INDUSTRIES, INC. - CONFIDENTIAL

  19. Product Installations • Inert gas distribution system installed by a large contractor in Texas in a busy shop environment • 2000 feet of copper tube and fittings from ½ - 1” • Workers noted the system went in faster than other alternative joining systems MUELLER INDUSTRIES, INC. - CONFIDENTIAL
