Pink is thicker and more durable - yellow is the thickest but I have not found a gun I can use it in yet... I have been using white in the White but last night when I put mine back together I decided to try the pink... It when in just fine - I'll let you know how it works... I use pink in the Remington's and the A&H's - but I have to use white in the Omega - the breech plug is tighter. A big key is not to tear the tape on the way in. That is why I suggest you spin and push the tapedown into the threadsbefore you install it. You should look down the barrel with a pen light and make sure that you can see teflon all the way around the bottom of the barrel on the face of the breech plug.
