J.W. Harris Stay-brite 8 1/8" 1#10009 (348-SB861) Category: Solder Alloys and Fluxes

Work as charm, you don’t need high temp to solder it

Extremely strong solder that will even allow you to eliminate brazing on AC linesets. Originally I was skeptical to use it on A/C linesets because of high pressures and vibrations but Stay bright 8 has pass every test with flying colors.

Good quality, great price, fast shipping....using this beats brazing

I installed a new set of coils in my house and used this product with a map gas torch to solder lines together. The silver wicks up quickly and fills the joints. Pulled a vacuum with a CPS VG200 micron gauge showing no leaks from soldering. AC works great now that its in the 90's outside and cool 75 inside.

We installed a 4 ton unit and used Stay Brite 8, perfectly. Just need correct preparation. Here some data from Harris: PHYSICAL PROPERTIES: Solidus 221°C (430°F) Liquidus 279°C (535°F) Deposit color – silver Shear Strength (copper lap joint) – 10,600 PSI Electrical conductivity (%IACS) – 16.4 Density (lbs./cu.in.) – 0.271 SOLDERING PROPERTIES: Stay Brite #8 is a lead free solder engineered to provide a strong, ductile connection on copper, brass, steel, and stainless steel. The silver color is also a good color match to stainless steel. Stay Brite #8 differs from Stay Brite as its higher silver content provides a melting range vs. Stay Brite’s single temperature melting point. The melting range makes it suitable for soldering connections with a wider clearance. Stay Brite #8’s low temperature characteristic promotes capillary flow and less base metal distortion and oxidation. Stay Brite #8 is often selected for residential HVAC tube connections as an alternative to brazing.
