Part of the NIBCO PC633-4 Press System series, this union allows plumbers and pipefitters to transition between a press-style connection and a threaded connection without using solder, flux, or open flame. That makes it a smart choice for retrofit work, repairs, and installations in areas where hot work permits are restricted or inconvenient. The fitting uses an inboard bead and an EPDM O-ring seal. When a pressing tool is applied, pressure drives the O-ring tightly against the copper tube, creating a watertight, leak-free joint in seconds. This dramatically reduces labor time compared to traditional solder unions. The union design allows the line to be separated and rejoined without cutting pipe or damaging surrounding connections, which is critical during system repairs and maintenance on copper water lines. The UCMIP34 is manufactured from ASTM B75 Alloy C12200 wrot copper, a material known for its durability, corrosion resistance, and suitability for potable water systems. It is lead-free and dezincification resistant, meeting modern plumbing code requirements for water quality and safety. The fitting carries third-party certifications to NSF\/ANSI 61 Annex G, UPC, CSA MSE 13, and PS-117, confirming it meets strict standards for use in drinking water applications. With a pressure rating of 200 psi cold working pressure and a temperature range of -20 degrees F to 250 degrees F, this union performs reliably across a wide range of residential and commercial plumbing conditions. HVAC technicians, plumbers, and mechanical contractors working with copper press systems will find this fitting compatible with standard press tooling and engineered for long service life in demanding environments.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePress x Male NPT union allows connection between press-fit and threaded copper pipe systems without soldering or flux\u003c\/li\u003e\n\u003cli\u003eEPDM O-ring and inboard bead design creates a watertight seal in seconds using a standard pressing tool\u003c\/li\u003e\n\u003cli\u003eThird-party certified to NSF\/ANSI 61 Annex G, UPC, CSA MSE 13, and PS-117 for potable water use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe NIBCO UCMIP34 delivers a fast, code-compliant transition between press and threaded copper connections, rated to 200 psi and suitable for potable water systems.
