Axial Type Brass Slip Sleeve Fittings (Press Fittings) made by our company RTP. Designed to connect polyethylene pipes when installing hot and cold, drinking water supply, radiator heating, underfloor heating systems and snow melting. The connection is carried out by a special assembly tool. Axial fittings are made of special hygienic brass CW617N, resistant to corrosion and provide a durable connection to the pipe.

The most prominent features:
- Axial Fittings is a Sliding Sleeve system.
- Designed with body insert that allows a turn of the fitting once installed, maintaining all its characteristics without losing the water tightness.
- Made of CW617N brass, compatible with PEXa, PEXa EVOH and PE-RT pipes.
- Full compatibility with commercially available tools.
- Range: Ø 16 to Ø 40 mm.
- Maximum temperature: 95º C.

Why compression fittings made by our company RTP?
- RTP's compression fitting system is a universal system for bathroom and central heating applications. All compression fitting components fit together perfectly. That ensures you can always count on safe and trouble-free installation.
- The extensive compression fitting program ensures you can quickly install every conceivable combination. We have every type of compression fitting, a comprehensive fitting system from 16mm to 40 mm to maximize the options.
- The RTP compression fittings are manufactured to unlimited perfection. We use the highest-quality brass with tolerances down to a five-hundredth of a millimeter. That ensures unrivalled quality. Down to the smallest details.

RTP compression fittings are characterized by their very simple and reliable connection technology. It means that both polyethylene flexible pipes and central heating pipes can be compressed on a single fitting. Our PE flexible pipe and compression fitting have the following qualities:

- A very long sealing surface (19-50mm) and no narrowed bore like other push-in fittings.
- No O-ring seals. The expanded memory effect plastic ensures 100%-sealed connection.
- During compression, the sleeve pushes the pipe towards the compression fitting. That provides a safe connection that is easy to check visually.

Saddle clamp fitting is a part of threaded polymer fittings which made from high-density polyethylene (HDPE) pipes. They are now available in diameters from 20 to 110 mm, with thread sizes from 1/2" to 2", and in 24 different options.

The RTP fitting is a threaded connection “Saddle Clamp” consisting of two parts that are securely joined. One part has a threaded elbow for the connection. The fitting is sealed by a rubber O-ring (gasket) that is fixed to the base of the elbow.

Sometimes it may be necessary to connect to an existing pipeline. In this case, the fitting elbow is the ideal solution.

This fitting offers several advantages, including:

✔ Easy installation in tight spaces such as bathrooms, hallways, etc.
✔ No need to shut off the water supply during installation.
✔ Low cost.
✔ Installation without the need for special tools.

Two GOST Standards for Ball Valves ⚙️

Currently, there are two active state standards for ball valves:

* GOST 21345-2005
* GOST R 59553-2021

For convenience, we can refer to the first as the “old” standard and the second as the “new” one, and explain the difference in simple, clear terms 🙂

Let’s start with the key point: the new standard does not replace the old one; it complements it.

Previously, there was a single standard, GOST 21345-2005, which applied to all types of shut-off valves up to 250 bar (PN 250) and up to DN 500. In essence, it covered everything from household valves to industrial-grade solutions.

Now, a separate standard has been introduced: GOST R 59553-2021, specifically for household brass ball valves up to 40 bar (PN 40) and up to DN 100. These are the valves commonly used in homes, apartments, and plumbing systems. This standard was introduced to improve user convenience and safety 🛡️

This is logical, because a ball valve is a point where the interests of installers and everyday users intersect. Mistakes here are unacceptable, so the requirements have been strengthened 👍

The new standard consolidates key requirements from various standards and adds its own. As a result, it ensures stricter quality control and improved design requirements.

What does this mean in practice?
— Increased flow passage
— Thicker wall construction
— Reinforced body
— Overall more reliable design 💪

Separate testing procedures are defined 🧪:
strength testing, tightness/leakage testing 💧, climate resistance 🌡️, service life testing, coating quality, and resistance to external loads. In other words, it is not only about pressure testing, but also bending, tensile strength, and coating quality 🔍

An important point is mandatory certification.
Our products have successfully passed certification ✅ and are already being supplied to construction sites, retail stores, and DIY networks inside Russia—where reliability and safety are essential.

Tips for Installing Polypropylene (PP) Compression Fittings with High-Density Polyethylene Pipes (HDPE)

Polypropylene (PP) compression fittings are one of the easiest ways to connect HDPE pipes, as they do not require welding equipment or special tools.

The operating principle is simple: a clamping collet. Inside the fitting is a clamping collet made of condensed polymer. When the nut is tightened, this collet mechanically secures the pipe and creates a tight connection. Additionally, a rubber gasket ring ensures a perfect seal.

The installation procedure is also simple:

⏺ Place the nut on the pipe.
⏺ Put on the collet.
⏺ Insert the pipe into the fitting until it stops, pressing it through the gasket ring.
⏺ Tighten the nut to secure the collet.

Important Note on Silicone Grease: Applying silicone grease to the pipe before installation will facilitate the process. This speeds up the installation and extends the life of the seal, as it keeps the rubber moist and prevents it from drying out.

RTP Compression Fittings Production Line

Our company manufactures PP compression fittings up to 110 mm in diameter and high-density polyethylene (HDPE) pipes up to 63 mm in diameter. We have all the necessary fittings in stock: reduction fittings, T-fittings, and couplings.
