  • Fits 14 to 16 inch pipes for versatile sealing
  • Holds 20 psi air pressure for reliable testing
  • Withstands 30 ft water head for hydrostatic checks
  • Deflates to 8.25 inch diameter for easy insertion
  • Single chamber design simplifies inflation and use

Test Plug for 14 to 16 Inch Pipes

The Safe-T-Seal TP1416 is a pneumatic test plug designed to seal pipes with inside diameters between 14 and 16 inches. It suits maintenance crews and contractors who need a temporary blockage for pressure testing or flow isolation. The single inflation chamber simplifies setup on site. Its rubber body and handle strap allow repeated use in demanding environments.

Pressure Limits and Deflated Profile

The plug withstands up to 20 psi of air back pressure and 30 feet of head in water applications. When deflated it measures 8.25 inches in diameter and 24 inches long, easing insertion through cleanouts or manholes. Inflation extends the length to 28.13 inches to engage the pipe wall securely. A female NPT air connection of 33/64 inch accepts standard inflation hoses.

Included Handle and Strap

The head tether combines a handle and strap so the plug can be lowered, positioned and retrieved without additional tools. This integrated attachment reduces the risk of losing the device in deep or vertical pipe runs. No separate inflation hose or pressure gauge is supplied with the unit. The product carries California Proposition 65 warnings for cancer and reproductive harm.

Questions about this item

How do I install the TP1416 test plug in a 14 to 16 inch pipe and what step is most often missed?

Deflate the plug to its 8.25 inch diameter, insert it into the pipe, then inflate through the 33/64 inch female NPT air connection until the plug seals; the step most often missed is verifying the pipe inside diameter falls between 14 and 16 inches before inflation.

What maintenance or replacement will the TP1416 pneumatic test plug need over time?

Inspect the single rubber inflation chamber and the head tether handle and strap for cracks, cuts or abrasion before each use; replace the plug if the rubber shows degradation or if it no longer holds the rated 20 psi air or 30 ft of water head pressure.

What is the first limit reached on the TP1416 test plug during sustained pressure testing?

The maximum back pressure ratings — 20 psi for air and 30 ft of head for water — are the first limits encountered; exceeding either can cause the single inflation chamber to fail.
