16mm PEM fitting with 3/4" G thread and TPU seal

Title:
PEM Hose Connector with TPU Seal – 16mm to 3/4" G Thread

Description:
This is a robust, watertight connector designed for 16mm PEM hose and standard 3/4" G (garden hose) threads. The model includes an integrated TPU sealing element for optimal leak protection.

Key Features:

• 💧 Watertight – Thanks to the TPU seal, the connection remains secure and leak-free.
• 🔄 No Hose Twisting – When tightening the threaded connection, the PEM hose remains stationary.
• 🧵 Standard Threading – Compatible with typical garden hose systems using 3/4" G thread.
• 🛠️ Sturdy Design – Engineered for strength and durability under repeated use.

This model is ideal for garden irrigation setups, DIY water systems, or any use case where a secure and reusable PEM connection is needed.

Assembly Instructions:
1:Insert the bottom part first, then feed the 16mm (14mm inside) PEM hose through it.

2:Push the TPU fitting in as far as possible by hand. Make sure it doesn’t twist inside the hose.

3:Use a 9mm drill bit to slowly drill into the center of the TPU part. The drill bit will grip the TPU and gradually pull it in. Soap can be used as a lubricant.

4:Carefully reverse the drill while holding the TPU part in place. Be cautious not to injure yourself – use thick gloves for safety.

5:Attach the front part of the connector and screw it in until it gently touches the TPU seal – don’t overtighten it yet (you’ll tighten it fully later).

6:Insert the TPU sealing ring into place.

7:Connect the assembly to the fitting where you want the PEM hose attached.

8:Now tighten the front part fully, so the TPU seal is pressed snugly into place. This step is done last to prevent the seal from twisting while connecting the hose.

9:Secure the connector with an M5 screw. There are also two additional holes available for smaller screws if needed.

✅ DONE!
You now have a watertight connection!
Double-check for any leaks and retighten if necessary.
