TH, V, U, M or UP? The profile depends on your fitting, not your press tool. Pick your fitting brand and system below, you'll see instantly which profile (and which insert) you need.
TH, V, U, M and UP: what's the difference?
A press profile (or press contour) is the shape in the insert that matches the fitting. Which profile you need depends on the pipe material and the fitting:

Which profile for which fitting brand?
Henco → TH
Viega (Profipress, Prestabo) → V
Geberit (Mapress) → M
Bonfix → TH or U (multilayer) · M (metal)
VSH → TH/U (MultiPress) · M (XPress) · V (Sudopress)
Wavin (Tigris) → TH or U, sometimes UP
Uponor → UP (S-Press Plus) or U (older MLC), see warning
⚠ Uponor: U or UP? Uponor fittings are often marked "U16", but the newer S-Press Plus must be pressed with the UP profile, not the regular U profile. U looks like UP, but can cause leaks over time. In doubt? Check before ordering.
Which profile for which material?
Copper, stainless and steel → usually M or V
Plastic and multilayer pipe → usually U or TH
The fitting manufacturer determines the final profile, check the fitting or the packaging. With the complete set (TH, V, U and M, 19 inserts) you press virtually every fitting, whatever the brand.
What does TH 16 or V 15 mean?
The letter is the profile (TH, V, U, M or UP) and the number is the pipe size in millimetres. TH 16 = a TH insert in size 16 mm; V 15 = a V insert in 15 mm.
Frequently asked questions
The fitting determines it, not the press tool. Copper/stainless → M or V, plastic/multilayer → U or TH. Use the checker at the top for your brand.
The newer Uponor S-Press Plus presses with UP, older MLC with U. Despite the "U16" marking, UP is often correct. Checking first prevents leaks.
Usually M or V, depending on the brand (Geberit Mapress = M, Viega Profipress = V).
The letter is the profile, the number is the pipe size in mm. TH 16 = TH insert 16 mm.
