A Comprehensive Choice Of Novopress Products
Engineered to deliver precise mechanical force, Novopress press tools and jaws are trusted by commercial mechanical contractors, domestic heating engineers, and facilities maintenance personnel who require permanent, leak-free connections for metallic and multi-layer pipe networks.
Novopress press fit kits provide installers with a tool and compatible jaw set for common press-fit applications. The BES range includes ACO103, ACO203, ACO203XL and profile-specific kits for M profile and U profile pipework systems.
The Novopress ACO103 is designed for smaller nominal widths, with Novopress stating suitability up to 35 mm for metal pipe systems and up to 40 mm for plastic or composite pipe systems. It has a 19 kN piston force, 30 mm piston stroke and uses the Milwaukee M12 battery system. For larger applications, the ACO203 and ACO203XL ranges offer increased capacity. Novopress lists the ACO203 with a 32 kN piston force and nominal widths up to 54 mm for metal systems, depending on the pipe system, while the ACO203XL is designed for metal pipe systems up to 108 mm and plastic pipe systems up to 110 mm.
M profile jaws are a core part of the BES Novopress range, with options covering common trade sizes from 15 mm to 54 mm, plus larger collars for selected M-profile copper fitting systems. These jaws are used where the pipe fitting manufacturer specifies an M profile press. We list M profile PB1 jaws, M profile PB2 jaws, standard M profile jaws and M profile angled jaws. Sizes include 15 mm, 22 mm, 28 mm, 35 mm, 42 mm and 54 mm, depending on the jaw type.
Choose an M profile jaw by matching four details: the press tool model, the pipe diameter, the fitting system and the jaw series, such as PB1, PB2 or compatible adaptor jaw configuration.
Novopress U profile jaws are available at BES in sizes including 16 mm, 20 mm, 25 mm and 32 mm. U profile jaws are used with compatible press-fit systems that specify a U profile pressing contour. The jaw profile must match the fitting system. M and U profile jaws are not interchangeable unless the fitting manufacturer explicitly confirms compatibility. Using the wrong jaw profile can result in an incomplete or unsuitable press joint.
Novopress angled press jaws are useful where access is restricted, such as pipework close to walls, floors, corners, joists, plant room equipment or existing services. Our range includes angled M profile jaws in 15 mm, 22 mm, 28 mm and 35 mm sizes, plus an angled press jaw set for 15 mm and 22 mm M profile work with an ACO103 adaptor.
Angled jaws can help installers maintain correct tool positioning when a straight jaw cannot be aligned properly around the fitting. Always check the tool, adaptor and jaw combination before use.
Adaptor jaws allow compatible Novopress tools to work with selected jaws, slings, collars or press rings. The BES range includes adaptor jaws for ACO203 tools, ZB221 and ZB222 adaptor jaws, and angled adaptor jaws for ACO103 and ACO203 press tools.
BES also supplies collars, including the Novopress M67 collar for Pegler Xpress copper fittings and the Novopress M76 collar for M-profile copper fittings in 76.1 mm. These are used for larger diameters or system-specific applications where a standard jaw is not suitable.
About Novopress
Novopress specialises in the design and manufacture of specialised tool systems for pipe-connecting technology. With an engineering-first approach, the brand develops battery-powered press machines (the ACO series), matching pressing jaws, adaptors, and slings. Their design philosophy centres on automated mechanical safety, ergonomics, and repeatable electronic calibration.
By eliminating the variables associated with manual jointing or open flames, Novopress systems help tradespeople meet strict structural compliance codes across domestic hot/cold water, commercial gas distribution, industrial cooling, and district heating installations.
How To Choose The Right Novopress Jaw Or Kit
Selecting the incorrect tool, jaw class, or profile can lead to permanent joint failure or mechanical damage to the pressing machine itself. Installers should evaluate three core parameters to correctly configure their on-site setup.
Match the fitting profile
Installers need to first identify the exact brand and mechanical profile of the press fittings used in the piping system. Selecting M Profile Jaws is required when installing metallic press systems, including copper, carbon steel, or stainless steel networks from manufacturers such as Pegler. Conversely, choosing U Profile Jaws is necessary when installing multi-layer composite plastic (MLCP) piping systems that require a plastic-oriented crimping profile.
Match the jaw class to the press machine
Novopress tools are grouped into distinct mechanical classes based on tool dimensions and hydraulic force capacity, so jaws cannot be interchanged between machine sizes. The PB1 Jaw Series is engineered exclusively for compact press machines such as the ACO103, handling smaller pipe diameters up to 35mm for metallic systems and 40mm for plastic lines. Standard commercial installations up to 54mm require the larger PB2 Jaw Series, which is designed to fit standard-sized tools like the ACO203. For large-diameter pipelines exceeding 54mm, such as 67mm and 76.1mm frameworks, operators must select specialised Pressing Collars and Slings activated via ZB intermediate adaptor jaws and paired with a 32 kN standard or XL press tool.
Evaluate physical space constraints
Reviewing the structural layout of the pipeline routing determines the physical form of the required tooling. Standard straight press kits operate efficiently along open, unhindered pipe runs, but restricted structural areas require adaptable configurations. When pipework is positioned inside narrow service risers, close to masonry backings, or directly behind pre-installed water cylinders, selecting an Angled Press Fit Jaw paired with a matching Angled Adaptor Jaw allows the tool body to rotate safely away from obstructions, preventing mechanical misalignment or incomplete joint compression.
Novopress Tool Maintenance & Calibration
Press tools and jaws should be kept clean, inspected regularly and maintained in line with Novopress and fitting manufacturer instructions. Worn, damaged or incorrectly maintained jaws can affect pressing quality and should not be used. Installers should check the tool’s service indicator, battery condition, jaw condition, retaining bolts and pressing surfaces before use. For commercial or safety-critical systems, maintenance records can help support quality assurance and project documentation.

FAQs
How do I choose the right Novopress jaws for plumbing?
Choose the jaw by matching the fitting manufacturer’s required profile, pipe diameter, press tool model and jaw series. For example, an M profile fitting normally requires the correct size M profile jaw, while a U profile fitting requires the correct size U profile jaw.
What is the difference between M profile and U profile jaws?
M profile and U profile refer to different pressing contours. They form the joint in different ways and are used with different press-fit systems. Always use the jaw profile specified by the fitting manufacturer.
Are Novopress tools compatible with copper, stainless steel and multi-layer pipe?
Compatibility depends on the tool, jaw, pipe system and the fitting manufacturer’s approval. Novopress lists applications for selected tools across metal, plastic and composite pipe systems, but the final selection must be checked against the specific press-fit system.
What is the difference between ACO103 and ACO203 press tools?
The ACO103 is a compact tool for smaller dimensions, with Novopress listing capacities of up to 35 mm for metal pipe systems and up to 40 mm for plastic or composite pipe systems. The ACO203 is intended for larger applications, with Novopress listing metal pipe capacity up to 54 mm, depending on the system, and plastic pipe capacity up to 110 mm.
What is the ACO203XL used for?
The ACO203XL is used for larger pressing applications. Novopress lists it for metal pipe systems from 12 mm to 108 mm and plastic pipe systems from 14 mm to 110 mm, with a 32 kN piston force and 80 mm piston stroke.
Do Novopress tools need servicing or calibration?
Yes. Press tools and jaws should be inspected and maintained according to manufacturer guidance. For ACO/ECO203 tools, Novopress refers to a 2-year maintenance interval. Always follow the tool manual and any service prompts.
What is the warranty period for Novopress press tools?
Most Novopress new pressing devices, tools and accessories have a 24-month statutory warranty. Conditions may apply, so check the latest Novopress and BES warranty information before purchase.
