Complete Guide to Connectors, Couplings and Plumbing Parts

The Fittings category brings together a wide selection of fittings and related components designed for plumbing, heating, gas, and industrial fluid systems. Here you will find pipe fittings, couplings, elbows, tees, adapters, valves, compression and push-fit connectors, as well as specialty pieces for HVAC and irrigation. Each product is described with technical details to help professionals and DIY enthusiasts choose the right part for installation or repair.

Types and Variants of Fittings

Fittings vary by design, material and connection method. Understanding the main types helps you quickly locate the correct item for your project.

  • Material-based:
    • Brass — durable and corrosion-resistant, common for potable water and gas.
    • Stainless steel — high strength and chemical resistance for industrial use.
    • Plastic (PVC, CPVC, PEX) — lightweight and cost-effective for drainage and water supply.
  • Connection method:
    • Threaded (BSP/NPT) — standard for many mechanical systems.
    • Compression — reliable for metal and plastic tubing without soldering.
    • Push-fit — fast, tool-free installation for repair or retrofit.
    • Soldered/Brazed — permanent, used in copper piping and HVAC refrigerant lines.
  • Functional forms:
    • Elbows, Tees, Crosses — change direction or split flow.
    • Reducers and Adapters — connect different sizes or types of pipes.
    • Valves and Stops — control flow and provide shut-off points.

Where Fittings Are Used

Fittings are essential across residential, commercial and industrial settings. Common applications include:

  • Household plumbing: water supply, drainage and fixtures.
  • Heating systems: radiators, boilers and underfloor heating circuits.
  • HVAC and refrigeration: refrigerant lines and condensate drains.
  • Irrigation and agriculture: durable connectors for outdoor systems.
  • Process and manufacturing: chemical, pneumatic and hydraulic lines.

How to Choose the Right Fitting

Selecting the right fitting reduces leaks and avoids premature failures. Follow these practical steps:

Measure and match

Confirm pipe diameter and wall thickness, and match thread type (BSP vs NPT) or connection standard for compatibility.

Consider material and environment

Choose brass or stainless for corrosive or high-temperature conditions; plastics for non-pressurized or cold-water lines.

Check pressure and temperature ratings

Verify operating limits and certifications (e.g., WRAS, NSF) for potable water or gas systems.

Installation and maintenance

Decide whether you need a quick push-fit, a reusable compression joint, or a permanent soldered connection based on access and serviceability.

Frequently asked questions about the Fittings category

Fittings — what exactly are they?

Fittings are pipeline components: reducers, tees, elbows, caps and nipples used to change direction, diameter or connect valves and accessories; commonly made from brass, steel, PPR or PEX-AL-PEX and designed to meet industry standards.

Fittings GOST — which standards apply?

Fittings follow material-specific standards: steel and brass fittings have metalwork standards, while PPR and PEX‑AL‑PEX follow polymer/laminate specifications. Check product markings and certificates for compliance.

Valves and fittings — how do they differ and how to ensure compatibility?

Valves control flow while fittings change direction or diameter. Ensure compatibility by matching connection types (compression 12 mm, press 16/20/25 mm, threaded 1/2") and using compatible materials like brass, copper, PPR or PEX‑AL‑PEX.

What is included in fittings — main product list?

Includes tees, elbows, reducers, nipples, end caps, couplings, threaded adapters and press/compression fittings for PEX‑AL‑PEX and PPR. Also seals and compression rings, e.g. copper pipe ring 12 mm.

How to choose fittings by material: brass, steel, PPR, PEX‑AL‑PEX?

Brass is ideal for threaded joints and valves; steel for high‑pressure mains; PPR for hot water and chemically neutral media; PEX‑AL‑PEX for flexible heating circuits. Consider operating temperature, pressure and corrosion resistance.

What connection types exist — press, compression, threaded — which to choose?

Press fittings (16/20/25 mm) are fast and solder-free; compression suits copper pipes (compression ring 12 mm); threaded (1/2", 3/4") allow removable joints. Choose based on pipe material and installer skill.

How to determine correct fitting size for pipes (diameters and connections)?

Check the pipe's inner/outer diameter and connection type: PEX‑AL‑PEX sizes use mm (16, 20, 25), threaded use inches (1/2, 3/4). Product descriptions list exact sizes and connection type.

Which fittings are suitable for heating systems and underfloor heating?

Use PEX‑AL‑PEX pipes and press fittings (16–25 mm), tees and reducers for distribution, plus press seals (PRESS KUMMITIHEND) for leak‑proof joints. Choose items rated for system temperature and pressure.

Can fittings of different materials be combined (brass with PEX‑AL‑PEX etc.)?

Yes, but use proper adapters like a PPR Transition VK 20x3/4 or brass coupling. Ensure correct seals and consider corrosion and thermal expansion differences.

What accessories are required for installing fittings (seals, compression rings, press sleeves)?

Common accessories: PRESS KUMMITIHEND seals for PEX‑AL‑PEX, compression rings for copper (12 mm), press sleeves and adapters. Product descriptions state included parts and required seals.
