Common Applications

The YKLZS1-T02 is a transparent acrylic stop plug machined with a G1/4 male thread for sealing any unused port on a reservoir, radiator, distribution plate, or water block. The clear acrylic body lets the plug blend into a hardline build instead of leaving a metallic cap visible. The head carries a wide coin slot so the plug can be seated finger-tight and snugged with a coin if needed. An O-ring at the thread base provides the seal against the port face; do not over-torque since the acrylic body can crack under excessive load. Sold individually; a typical reservoir build uses two to four plugs.

Frequently Asked Questions

Q: What port size does this plug fit?

A: Standard G1/4 inch, the universal water cooling port size on blocks, reservoirs, radiators, and distribution plates.

Q: What material is the plug?

A: Transparent acrylic body with a rubber O-ring at the thread base.

Q: How is the plug tightened?

A: Coin slot in the head: finger-tighten first, then snug with a coin. Do not use heavy pliers; the acrylic can crack.

Q: How many plugs ship per unit?

A: One plug per order. The 4-pack listed on Amazon is a separate retailer bundle.

Q: Will it seal under loop pressure?

A: Yes when seated against the port O-ring. As with any acrylic fitting, inspect for stress cracks after install and during leak testing.
