Lyreh RV Low-Point Drain Plugs & Caps for 1/2" Hot & Cold Lines — 2-Set with Sealing Rings & Thread Tape

Keep your travel trailer, camper or RV water system ready for winterization, maintenance or leak prevention with this compact, ready-to-install kit from Lyreh. Designed for 1/2" hot and cold lines, the set contains two full low-point drain assemblies so you can service both supply lines or keep a spare on hand. Constructed from ABS, stainless steel and durable plastic, the components are made to resist wear and repeated removal while forming a secure seal that helps prevent drips and antifreeze loss.

How do these drain plugs stop leaks on an RV water system?

The included sealing rings and precisely fitted caps create a tight closure on 1/2" low-point drain ports. Properly seated seals compress to block water passage and the tape helps ensure threaded components sit flush without cross-threading.

• Sealing rings sized for 1/2" lines to prevent water seepage
• Durable ABS and stainless elements resist deformation
• Thread tape included for leak-free screw-in installation

Can I use this kit for both hot and cold water lines?

Yes — the Lyreh set is compatible with standard 1/2" hot and cold low-point drains found on many RVs and travel trailers. Each kit provides two complete drain plugs and caps so you can equip both lines at once or save one set as a spare replacement.

• Two full plug-and-cap assemblies for dual-line coverage
• Universal fit for common 1/2" low-point ports
• Replacement-ready parts to match typical RV plumbing layouts

How easy is installation and maintenance?

Installation is straightforward and can be completed without special tools: remove the old plug, fit the sealing ring, apply the tape to threads if needed, and tighten the new cap. Regular inspection and occasional replacement of the sealing rings keep the connection watertight and extend service life.

• Simple screw-in replacement for lost or damaged plugs
• Includes thread tape so you can install immediately
• Low-profile cap design for easy manual removal when draining

What materials and sizes are included in the package?

The kit contains components sized to match typical drain ports: caps, plugs and sealing rings designed for reliable contact and longevity. Materials chosen blend corrosion resistance and impact durability for outdoor and seasonal use.

• Package: 2 drain plugs, 2 caps, 2 sealing rings, 2 tapes
• Cap size: 2.6 x 2 cm; seal size: 1.9 x 1 cm
