Female Adapter, Slip x FPT PVC Schedule 40 6" (435-060)
$24.24
The 435-060 is a 6" Schedule 40 PVC Female Adapter with a Slip x FPT configuration. This fitting transitions a cemented PVC pipe run to a threaded connection at the same nominal size — the slip socket accepts 6" PVC pipe for solvent cementing on the pipe side, while the Female Pipe Thread (FPT) outlet on the opposite end receives any male-threaded (MPT) fitting, valve, pump flange adapter, or equipment port of the same nominal size. No size reduction occurs; the female adapter is a same-size connection-type transition fitting, converting a permanent cemented pipe end into a serviceable threaded port at full bore.
The female adapter occupies a distinct and essential role in PVC pressure piping systems. Where a coupling joins two cemented pipe ends and a union provides a disassemblable break point within a cemented run, the female adapter is the boundary fitting — it terminates the cemented pipe system at a defined point and presents a threaded female port for connection to whatever threaded component, valve, or equipment lies downstream. Once the adapter is cemented to the pipe, the FPT outlet functions exactly as a threaded port would in any other context: it can receive and release male-threaded connections repeatedly without disturbing the cemented pipe assembly upstream.
At 6", the 435-060 is a large-format adapter sized for high-volume commercial and industrial piping applications. The 6" female adapter is most commonly encountered at the interface between large-diameter PVC distribution mains and the threaded inlets and outlets of major equipment — large pump housings, large ball valves or butterfly valves with threaded end connections, large filter vessels, flow meters, and storage tank ports — where the supply or distribution infrastructure is 6" cemented PVC and the equipment connection is male-threaded at the same nominal size. It also appears at flanged assemblies where a threaded nipple bridges the female adapter to a companion flange fitting, and at system endpoints where the 6" cemented main must terminate at a threaded isolation valve or equipment inlet.
The same-size configuration — 6" slip to 6" FPT — means no flow restriction occurs at the adapter. The full bore of the 6" pipe passes through the fitting unobstructed, and the FPT outlet presents the same nominal bore to the downstream connection. This distinguishes the female adapter from a reducing bushing (which changes size) and from a union (which provides disassembly within the pipe run) — the female adapter's sole function is the connection-type transition from cemented to threaded at the same pipe size.
At 6" diameter, the cemented slip socket requires careful solvent welding practice — thorough, even primer and cement coverage across the full socket interior and pipe end surface is essential given the significantly larger joint surface area at this size. A two-person assembly is recommended: one to apply cement and seat the pipe, one to hold alignment firmly through the full set period. Pipe must be inserted to full socket depth and held without rotation until the joint sets. Thread sealant tape (PTFE) or pipe dope rated for PVC service should be applied to all male threads assembled into the FPT outlet before installation, and downstream pipe or equipment weight should be supported independently rather than cantilevered from the adapter body.
Manufactured in white Schedule 40 PVC, the 435-060 provides solid corrosion resistance across a broad range of fluids and a substantially lower installed weight compared to cast iron or steel female adapters of equivalent size — a meaningful field handling advantage when working with 6" pipe and fittings on large commercial and municipal installations.

⚠️ Note: Apply PTFE thread tape or PVC-compatible pipe dope to all male threads assembled into the FPT outlet before installation. Do not over-tighten threaded connections into the FPT outlet — large-diameter FPT ports are susceptible to body cracking under excessive torque or uneven loading from unsupported downstream pipe weight; support downstream pipe runs independently. Use primer on both the slip socket interior and the pipe end before cementing — do not skip the priming step at 6" diameter. A two-person assembly is recommended at this size. Consult manufacturer derating tables for elevated-temperature service.
Industries & Applications:
- Municipal Water Distribution — Transitions 6" cemented PVC distribution mains to threaded equipment connections, isolation valves, and service fittings at points in the municipal distribution network where the cemented pipe system must interface with male-threaded valves, meters, or hydrant assemblies at full bore
- Irrigation & Agricultural Systems — Used at pump station outlets, large manifold terminations, and control valve inlets on high-volume agricultural, golf course, and commercial irrigation systems where a 6" cemented supply main must connect to the threaded inlet of a large valve, filter, or pump equipment port
- Water & Wastewater Treatment — Applied at the boundary between 6" cemented PVC distribution or process piping and the threaded inlet and outlet ports of treatment equipment — large filters, chemical injection points, flow meters, and pump assemblies — where the cemented pipe system terminates and the equipment connection begins
- Industrial Process Piping — Installed at equipment connection points on 6" process water, cooling water, and non-aggressive chemical mains where the cemented PVC distribution system must interface with male-threaded equipment ports, valves, and instrumentation connections at full 6" bore
- Pump Station & Equipment Connections — Connects 6" cemented PVC suction and discharge mains to the threaded inlet and outlet ports of large pump housings, creating the transition between the permanent cemented pipe assembly and the serviceable threaded equipment connection at each side of the pump
- Stormwater & Drainage Infrastructure — Used at outfall structures, inlet connections, and control points on large-diameter PVC stormwater conveyance systems where the cemented pipe run must transition to a threaded connection at a structure, headwall, or inline control device

Installation & Handling Tips
Proper installation provides you with a long-lasting, leak-resistant connection — especially when working with large-diameter Schedule 40 fittings. Follow these guidelines for a secure and stress-free setup:
- Clean and dry both the pipe and socket before priming.
- Apply purple primer and solvent cement per the manufacturer’s instructions; fully seat the pipe with even pressure.
- Use additional support if needed to keep the fitting aligned during solvent welding.
- Support the pipeline so system weight and vibration are not carried by the adapter.
- Use PTFE thread sealant on male threads; avoid petroleum-based pipe dopes.
- Hand-tighten first, then finish with a strap wrench to prevent over-torquing.
- Allow full cure time before pressure testing the line.
- Note: not for use in compressed air or gas systems.
