These will interchange with Snaptite H series, Perfecting V series, Faster TNV series, Tuthill TH Series, and PCI TNV series. The special 2-piece body permits a large flow passage thereby permitting greater flow while maintaining a low pressure drop. Both the coupler and the nipple are valved and built for heavy duty applications. The standard bodies are plated steel (brass and stainless are available on request, suffix BR and suffix SS) and come with a Buna-N seal (optional Viton seals available, suffix V). Replacement seal kits are available, which include Buna-N O-Rings and PTFE Back-up rings for both the coupler and nipple (part #VHCxx-SPK).
