Common Applications

The TBLDS is a low-profile G1/4 stop plug used to seal any unused G1/4 threaded port on a reservoir, pump top, water block, radiator or distribution plate. The body is solid brass with an electroplated finish and an internal hex drive on the face, so it can be tightened or removed with a hex key without needing clearance for an outer flange. A captive O-ring on the underside makes the seal, eliminating the need for thread tape. The flat low profile is useful where a standard rounded plug would foul an adjacent fitting, fan, or radiator end-tank.

Frequently Asked Questions

Q: What thread does it use?

A: G1/4, the standard PC water-cooling fitting thread. It will seal any G1/4 BSPP port on reservoirs, pump tops, blocks, radiators and distribution plates.

Q: How is it tightened?

A: With a hex key through the internal socket on the face. There is no outer flange to grip with fingers, which is what makes it ultra low profile.

Q: Do I need PTFE tape on the threads?

A: No. The seal is made by the captive O-ring under the head. PTFE tape is not required and can actually unseat the O-ring if over-applied.

Q: What is it made of and what finishes are offered?

A: Solid brass with an electroplated finish. Common variants are black, silver and white.

Q: How many plugs are in the package?

A: Single piece unless the listing specifies a multi-pack. Verify on the order page before checkout if you need a set.
