1/2" x 520" PTFE Thread Seal Tape White
Product Overview
A proven choice for creating leak-proof seals on threaded pool plumbing and equipment.
Pool techs reach for the American Granby HTT520 when installing pressure gauges or threaded PVC fittings because it provides a reliable, non-hardening seal. This 1/2" x 520" PTFE tape is UL Listed 31RO, ensuring it meets specific standards for pipe joint compounds in pressurized systems. Unlike generic tapes that can be overly thin, this specification handles the constant vibration and chemical exposure common in pool equipment pads.
Benefits & What Makes It Different
UL Listed 31RO Standard
This certification ensures the tape is rated as a pipe joint compound, providing peace of mind for high-pressure pool plumbing applications.
High-Density PTFE
The 100% PTFE material is chemically inert, meaning it won't degrade when exposed to high chlorine levels or acidic pool water conditions.
Extended 520-Inch Roll
The HTT520 provides enough length for dozens of equipment installs, making it a staple for service trucks and well-stocked pump rooms.
Compatibility
- Schedule 40 and 80 PVC fittings
- Stainless steel pressure gauge stems
- Brass and copper threaded pipe
When To Use This
Pro Tip
If you are sealing a plastic-to-plastic threaded connection, avoid over-tightening; the PTFE tape provides the seal, so hand-tight plus a quarter turn is usually sufficient to prevent cracking the manifold.
Common Questions & Instructions
How many times should I wrap PTFE tape around pool plumbing threads?
For standard 1/2 inch or 3/4 inch threaded fittings, we recommend 3 to 5 wraps to ensure a watertight seal without over-stressing the plastic housing or manifold.
Which direction do you apply the HTT520 thread seal tape?
Always wrap the tape in a clockwise direction (following the threads) so that it stays tight and flat as you screw the fitting into the female port rather than unravelling.
Can this tape be used on pool heater gas lines or just water lines?
While PTFE is versatile, the HTT520 is specifically UL Listed as a pipe joint compound for water systems; always check local codes for gas-specific yellow tape requirements for heaters.
