Product Description

Unasco Silver Stainless Steel Thread Seal Tape is a nickel infused thread sealing tape specifically made for stainless steel fittings. This tape prevents stainless steel fittings galling or seizing during assembly and disassembly. With the tape impregnated with nickel powder, it acts like bearing plates, which keep the surface of the male and female threads apart. The thickness of the tape provides even further protection due to its denser than average composition to ensure an effective seal. Features of the tape include its effectiveness across a wide range of temperatures(-450F - 500F) and prevents galvanic corrosion of threads. More benefits include no curing time, non-toxic, non-flammable, and has an unlimited shelf life.

Unasco Stainless Steel Thread Sealing Tape is recommended for stainless steel pipe and fittings but it is compatible with the following piping materials:

  • Galvanized Steel
  • Iron
  • Brass
  • Copper
  • Aluminum
  • Fiberglass
  • Polyethylene
  • Polypropylene
  • PVC
  • CPVC
  • ABS

Application Instructions

Fittings up to 1-1/2 inch / 38mm diameter

  1. Use 1/2 inch / 12mm wide tape.
  2. Clean the male and female threads thoroughly.
  3. Wrap the tape around the male thread. Take care to keep the tape under tension as you are wrapping so the tape moulds itself into the root of the thread.
  4. Make sure that you wrap with the thread.
  5. Make sure that the tape does not overlap the end of the fitting.
  6. Three wraps seal most threads.

For poor quality or damaged threads or threads that are hard to seal like parallel threads or threads on fittings subject to vibration, more than three wraps may be necessary.

Nominal Tape Widths vs Actual Widths

Nominal vs. Actual Widths Zoom In

Tape rolls are cut to standard tape industry metric widths of approx. 24mm per 1-inch of nominal width ordered. As a result ACTUAL tape widths are normally 5% narrower than the NOMINAL width shown in inches. Examples:

  • 1" Nominal width = 15/16" (24mm) Actual width
  • 2" Nominal width = 1-7/8" (48mm) Actual width
  • 3" Nominal width = 2-13/16" (72mm) Actual width

Note that tape rolls are NOT guaranteed to be splice-free.

Unasco Silver Stainless Steel Thread Seal Tape
Made in the USA
hot melt rubber (synthetic)
Offers the widest range of application flexibility available. Exhibits excellent processing performance whether manually or automatically applied. Has superior tensile strength, adhesion properties and holding force which ensures consistent, reliable seals. Hot melt adhesive will bond faster to a surface which is referred to as quick-grab or quick-stick. It typically has higher tack (will feel stickier to the touch), but is also softer. It has lower heat resistance, shear resistance, and sometimes UV resistance than an acrylic adhesive. NOTE: it is called hot melt because the adhesive is applied hot by the manufacturer and then hardens as it cools (you do not need to apply heat to the tape yourself).
natural rubber
Properties are similar to that of hot melt rubber, but natural rubber often holds where other adhesives won't (recycled fibers, dust, cold, heat and heavy loads). It provides good overall adhesion and moisture resistance.
acrylic
Offer excellent performance, especially for applications in temperatures less than 40°F and greater then 120°F. It provides excellent clarity, has high shear strength, is usually more permanent/durable even when exposed to moisture, and it ages well over extended periods in fluorescent and sunlight. Since it remains clear for the life of the application and does not yellow over time it is ideal for applications such as sealing white cartons. While it has good initial adhesion it does take 24-48 hours to cure and to achieve its maximum bond strength (has gradual adhesion buildup). Another difference between hot melt rubber and acrylic adhesive is if you fold tape over making the two adhesive sides touch the acrylic adhesive will remain attached to the carrier (e.g. paper, film) while a hot melt adhesive will stick to itself and pull off of the carrier. It is the best choice for clarity, UV resistance and aging characteristics.
silicone
Is great for extreme temperature applications since silicone adhesive can work in continuous operating temperatures from -100°F to 500°F. They also exhibit good chemical resistance, retain electrical properties, and remove cleanly with little or no residue.
zinc oxide
Zinc oxide based adhesive formula is a skin-friendly adhesive which is commonly used on sports medicine tapes.
Thickness, AKA caliper or gauge, refers to the distance from one surface of a tape backing, or adhesive, to the other.
1 mil = 1/1000 of an inch
Examples: 1/16 inch = 62.5 mils; 1/32 inch = 31.25 mils
