The body is solid molded PVC; the threaded end is male NPT; the head is a hex \/ square wrench drive.

Hand-tighten into the female port plus 1 to 2 turns with a wrench on the hex head — a strap wrench is safer on a PVC female port than a metal pipe wrench; an open-end wrench on the 450's hex head is fine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDO NOT over-tighten.\u003c\/strong\u003e The thread interference is what seals the joint, not the torque. PVC female threads on receiving ports (like a 435 adapter or a 401 tee branch) can split if the plug is cranked too hard. Hand-tight + 1 to 2 wrench turns is the target; if the joint weeps, replace the tape and re-thread — don't keep tightening. Over-tightening is the #1 cause of cracked PVC female-thread ports in the field.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHex head orientation:\u003c\/strong\u003e the head is symmetric — no installation orientation requirement.
