Why M Profile

Key Features & Advantages

The M Profile geometry is one of the most widely adopted press fitting standards in Europe and globally, offering outstanding sealing performance and tool compatibility.

Flameless Installation

No welding, no open flame -- press connection is completed in seconds, dramatically reducing installation time and fire risk on site.

Unpressed Detection

EPDM / HNBR O-ring design allows water to leak visibly if a fitting is not pressed, preventing hidden failures during pressure testing.

Visual Check Indicator Ring

Colorful visual check indicator ring optional. Peal off after pressing, which allows installors could easily identify unpressed fitting.

Wide Size Range

Available from 15 mm to 168.3 mm, covering residential plumbing through large commercial and industrial pipework.

Multi-Tool Compatibility

M Profile jaw sets are compatible with most major press tool brands, giving installers flexibility on site.

OEM / ODM Ready

Over 20 years of OEM/ODM manufacturing experience. Custom dimensions, markings, and packaging available for global distributors.

FAQ

Frequently Asked Questions

What is the M Profile and how does it differ from other press profiles?
The M Profile (also called the "M-contour") is a widely adopted press fitting geometry characterized by its distinctive hexagonal press point shape. It is compatible with a broad range of press tools and jaw sets from major manufacturers. Compared to other profiles such as TH or V, M Profile offers excellent versatility and is particularly popular in European and international markets.
Which O-ring material should I choose for my application?
PiPress M Profile fittings are available with three O-ring options: EPDM (black) is suitable for potable water, heating, and cooling up to 120°C; HNBR (yellow) is designed for gas applications (natural gas, LPG); and FKM/Viton (green) is recommended for oils, fuels, and chemically aggressive media. Always verify the O-ring colour coding before installation.
Can PiPress fittings be used with pipes from other manufacturers?
Yes, PiPress M Profile fittings are designed to work with stainless steel tubes conforming to EN 10312 (Europe) or ASTM A312 (USA/international). Pipe outside diameter and wall thickness must comply with the relevant standard. We recommend verifying compatibility before installation, especially for non-standard pipe sources.
Do you offer OEM / private label services?
Absolutely. With over 20 years of OEM/ODM experience, we can produce fittings under your brand name, with custom packaging, markings, and documentation. We work with distributors and brand owners in Europe, the Americas, Australia, and beyond. Contact our sales team to discuss your requirements.
What is the minimum order quantity (MOQ)?
MOQ varies depending on the fitting type, size, and whether OEM services are required. For standard stock items, smaller quantities may be available through our regional distributors. For OEM orders, please contact us directly with your specifications for a tailored quotation.
