⚡ At a Glance
- • Connection Type: 15mm compression to 3/8-inch BSP male thread, brass construction
- • Best for: DIY homeowners and plumbers fitting or replacing mixer taps
- • Not ideal for: Push-fit-only plumbing systems without compression fittings
Solid brass male compression couplings supplied as a pair for linking 15mm pipework to 3/8-inch BSP tap tails. Designed for straightforward use on GROHE kitchen and bathroom mixer taps.
Leak-resistant joints - with 15mm compression to 3/8-inch BSP male thread
Male compression couplings create a mechanical seal by tightening the nut onto a compression ferrule around the 15mm pipe, forming a secure joint with the male BSP thread. That sealing action relies on the ferrule compressing evenly onto the pipe bore.
Secure mechanical joints help reduce drips and minor leaks at tap tails, giving a dependable seal for household water pressure.
Long-lasting durability - with solid brass construction
Brass is commonly used in potable water fittings because it resists corrosion and maintains structural strength under normal domestic pressures. The metal body remains stable when exposed to hot and cold cycles.
Robust metal fittings lower the likelihood of cracking or corrosion, reducing the need for frequent replacements in kitchens and bathrooms.
Gentle on seals - with a smooth brass finish
A smooth machined finish minimises abrasion to rubber washers and seals during assembly and tightening, helping maintain their original sealing profile. Less abrasion preserves the integrity of existing seals.
Preserving rubber seals helps avoid unnecessary seal replacements and keeps joints watertight for longer.
