The MB Sturgis 100019-20 is a high-flow LP propane pigtail hose designed to connect a dual-cylinder propane system directly to a two-stage regulator. Its POL (Prest-O-Lite) inlet delivers a higher unrestricted flow than a Type 1 (QCC1) connection, making it the right choice when your RV appliances demand more BTUs than a standard connector can reliably supply.
When you run multiple LP appliances simultaneously -- furnace, range, water heater, and refrigerator -- a single standard hose and Type 1 fitting can restrict gas flow enough to cause burner lockouts, regulator bypass, and nuisance shutoffs. The POL connection on this MB Sturgis hose bypasses that bottleneck, delivering up to 500,000 BTU/hr of capacity through a 1/4-inch ID thermoplastic hose.
The 20-inch length is the standard "pigtail" format used on most coach and trailer dual-cylinder manifolds. One end threads onto a standard POL tank valve (left-hand thread, no handwheel needed); the other end terminates in a 1/4-inch male inverted flare for direct connection to a two-stage regulator or manifold inlet.
Left-hand threaded POL fitting with integrated excess-flow protection. Provides higher unrestricted flow than QCC1/Type 1 connections.
Industry-standard 1/4-inch male inverted flare outlet mates directly to two-stage regulators and dual-cylinder manifolds without adapters.
Rated -40F to 140F (-40C to 60C), suitable for cold-weather camping and warm-climate full-time RV living alike.
Meets UL569 and ANSI Z21.81 standards for LP hose connectors. Accepted by most campground inspectors and RV technicians.
An LP pigtail hose is the short flexible connector between each propane cylinder valve and the automatic changeover regulator or manifold. Most RVs ship with Type 1 (QCC1) pigtail hoses, which include a built-in excess-flow restriction rated around 200,000 BTU/hr. For rigs with a single burner or two small appliances, that is adequate.
On coaches with a furnace, 3-burner range, oven, tankless water heater, and absorption refrigerator all potentially drawing at the same time, the Type 1 restriction can trigger nuisance excess-flow lockouts even when the cylinder is full. Upgrading to POL pigtails like this MB Sturgis hose raises the practical flow ceiling substantially and eliminates most regulator bypass complaints.
This hose fits any standard POL cylinder valve (the most common valve type on 20 lb, 30 lb, and larger horizontal cylinders used on RVs). The 1/4-inch male inverted flare outlet is a universal size used by virtually all two-stage automatic changeover regulators and dual-cylinder manifolds from Cavagna, Marshall Excelsior, Rego, and similar brands.
If your regulator inlet accepts a different fitting type (such as 9/16-inch inverted flare or a 1/4-inch NPT female), an appropriate adapter fitting will be required -- not included with this hose.
