2. Applications in Domestic Water Supply Systems
 |
2.1 Residential Water Supply
MAYER stainless steel press fittings are suitable for domestic water distribution networks in apartments, villas, detached houses and multi-storey residential buildings. Elbows, tees and couplings connect branch pipes, change flow direction and distribute water to kitchens, bathrooms, washbasins, showers, toilets and laundry areas.
When used with compatible stainless steel pipes and correctly installed sealing components, press fittings provide secure mechanical connections for everyday water supply. Their corrosion resistance, durability and hygienic characteristics make them a practical choice for long-term residential plumbing systems.

2.2 Hot and Cold Potable Water Systems
In domestic hot and cold water systems, stainless steel press fittings are used to connect water supply pipes, branch lines and terminal connections. They are suitable for distributing cold water and hot water to household fixtures and appliances, subject to the design temperature, pressure rating and sealing material specifications.
Stainless steel offers good corrosion resistance and a durable internal surface. When the complete piping system uses appropriate potable-water-contact materials and complies with applicable local requirements, it helps maintain water quality throughout distribution.

 |
2.3 Apartment Buildings and High-Rise Residential Projects
Large residential developments require well-organized water distribution networks, including vertical risers, horizontal distribution pipes, branch connections and equipment-room pipework. MAYER stainless steel press fittings help connect these sections through a range of elbows, tees, couplings and reducers.
The press-fit installation method is particularly useful for projects involving multiple floors and numerous connection points. It eliminates on-site welding and can simplify installation planning, helping contractors manage labor, construction schedules and installation quality.

2.4 Domestic Water Distribution and Equipment Connections
Stainless steel press fittings can also be used in domestic water distribution branches and connections to compatible water meters, pumps, filtration units, storage tanks and water manifolds. They help create organized pipe layouts and facilitate connections between the main supply line and individual water-use points.
For equipment connections, the fitting type, thread standard, pressure rating and connection dimensions should be confirmed against the equipment manufacturer's specifications before installation.

3. Why Choose AISI 304 and AISI 316L?
 |
 |
| AISI 304 |
AISI 316L |
MAYER offers stainless steel press fittings in AISI 304 and AISI 316L to meet different domestic water supply requirements. Material selection should consider water chemistry, chloride concentration, installation environment, operating conditions and project specifications.
- AISI 304 Stainless Steel: A practical choice for many standard residential hot and cold water systems, offering good corrosion resistance, mechanical strength and durability.
- AISI 316L Stainless Steel: Contains molybdenum and has a lower carbon content than standard 316, providing improved resistance to certain forms of corrosion. It may be preferred in coastal areas or applications involving more aggressive water conditions, subject to engineering assessment.
Both grades can support durable domestic plumbing systems when selected and installed correctly. The appropriate material should always be confirmed against the actual water conditions and applicable project standards.

4. Press Connection Technology
MAYER stainless steel press fittings use a mechanical press connection designed for compatible stainless steel pipes and approved pressing tools. Depending on the product series, the connection incorporates a sealing element and a specially formed fitting profile. The pressing tool deforms the fitting around the pipe to create a secure mechanical joint and reliable seal when correctly installed.
The typical installation process includes:
 |
1. Cutting
Confirm the pipe length needed, and cut it with approved burr-free cutters.
Oxy-acetylene torches and abrasive cut-off wheels are not suitable.
|
 |
2. Deburring
Carefully deburr all pipe cuts inside and outside with a deburrer. Remove any cutting residue thoroughly.
|
 |
3. Assess and mark insertion depth
Mark the pipe with a fine-point felt pen where it meets the fitting for verification of full insertion.
|
 |
4. Check the o-ring
Check the positioning of the o-ring, and lubricate the o-ring with water or talc to ease insertion of the pipe if necessary. Make sure the pipe and fitting are clean and free of oil and sundries.
|
 |
5. Inserting the pipe into the fitting
The pipe is inserted in the fitting with a slight rotating motion until it hits the stop. Check the pipe against the felt pen mark to ensure complete insertion. And the insertion should not be forced at an angle, which will easily cause damage to the o-ring.
|
 |
6. Pressing
Position the jaw over the fitting, creating a perfect fit with the internal channel of the jaw around the toroidal seat of the fitting. Make sure that the jaws are perpendicular to the joint, and squeeze the trigger to initiate the press cycle, holding it down for the full duration of press cycle.
|
 |
7. Confirming the size of joint
Confirm the size of joint by measuring the section dimension with a special gauge.
|
Unlike welded connections, press fittings require no welding flame at the joint. This can reduce hot-work risks, simplify installation in confined spaces and improve construction efficiency. Installation must follow the product-specific instructions and local plumbing regulations.
