Heating and plumbing distributor Navigator has expanded its MB press fit fittings range, now available in larger sizes to cover more installation needs. The system, approved by both Kitemark and WRAS, offers installers a trusted alternative to traditional jointing methods, especially in projects where hot works are restricted or not practical. Designed for ease of use, the fittings feature a blue identification ring that drops off automatically once pressed, giving installers a clear visual confirmation. Unpressed joints remain visible, helping to reduce errors. The ring also carries the fitting size, helping to improve speed and accuracy when selecting parts.
